Resumen

Purpose – Logisticians in the worldwide industry are frequently faced with the problem of measuring the total cost of holding inventories with simple and easy-to-use methodologies. The purpose of this paper is to look at the problem, and in particular illustrate the inventory holding cost rate computation, when different kind of warehousing systems are applied. Design/methodology/approach – A multiple case study analysis is here developed and supported by a methodological framework directly derived from the working group discussions and brainstorming activities. Two different field of application are considered: one related to five companies with manual warehousing systems operating with traditional fork lift trucks; the other is among five companies operating with automated storage/retrieval systems (AS/RS) to store inventories. Findings – The multi-case study helps to understand how the holding cost parameter is currently computed by industrial managers and how much the difference between manual and automated/automatic warehousing systems impacts on the inventory cost structure definition. The insights from the ten case studies provide evidence that the kind of storage system adopted inside the factory can impact on the holding cost rate computation and permit to derive important considerations. Practical implications – The final aim of this work is to help industrial engineers and logisticians in correctly understanding the inventory costs involved in their systems and their cost structure. In addition, the multi-case analysis leads to considerations, to be applied in different industrial contexts. As other industrial applications are identified, they may be analyzed by using the presented methodology, and with aid from the data from this paper. Originality/value – The relevance of this work is to help industrial engineers and logisticians in understanding correctly the inventory costs involved in their logistics systems and their cost structure. In addition, the multi-case analysis lead to interesting final considerations, easily to be applied in different industrial contexts. As other industrial applications are identified, they may be analyzed by using the methodology and extrapolating the data from this paper.

Resumen

The main purpose of the study was to investigate the effect of physical distribution management on organizational performance by Rutungu Distributors Ltd, Kampala (U). The study assessed the relationship between order processing and organizational performance in Rutungu Distributors Ltd in an attempt to establish the relationship between storage and organizational performance in the organization. It also sought to find out the relationship between other aspects of inventory management on organizational performance within the company. The research used a case study design approach which was correlational considering both quantitative and qualitative approaches in the data collection, presentation, and analysis. The population of the study was several categories of employees of the company. Findings from the study depicted that there is a positive significant relationship between order processing and organizational performance implying that when a customer submits an order, it is verified to ensure the necessary information is included and processed promptly. Storage and organizational performance; this means that the company can reduce damage through good materials handling. There was a positive significant relationship between inventory control and organizational performance as a result of heavy investment in inventory control practices and procedures. There was also a positive significant relationship between transportation and organizational performance showing that the company has an effective automated transportation system, observes well-coordinated fleet management practices, and also has a good vehicle maintenance policy. The study thus recommends the company to continue reducing the time it takes to get an order to a customer’s premises and to replenish its stores as it is what every company desires, but while faster fulfilment and small order sizes make customers, and store managers happy, faster fulfilment comes at a cost.

Resumen

The MIDAS system is an automated supply chain management system that enables customers, manufacturers, and suppliers to cooperate over the Internet. MIDAS aims to achieve high customer satisfaction by supporting the build-to-order customization model and to reduce inventory carrying costs and logistics administration costs at the manufacturer by supporting the just-in-time manufacturing model. It allows a manufacturer to choose from the MIDAS Registry, suppliers of components, and negotiate based on the prices, availability, and delivery times of those components. The manufacturer can use one of several strategies to aggregate customers’ orders before processing them, and one of several strategies to accumulate suppliers’ quotes before deciding on a particular supplier. The paper presents an evaluation of these strategies in terms of the customer’s satisfaction, as measured by the customer response time, and the manufacturer’s gain, as measured by the number of orders aggregated or the best price ratio.

Resumen

The California State University, Northridge (CSUN) Oviatt Library was the first library in the world to integrate an automated storage and retrieval system (AS/RS) into its operations. The AS/RS continues to provide efficient space management for the library. However, added value has been identified in materials security and inventory as well as customer service. The concept of library as space, paired with improved services and efficiencies, has resulted in the AS/RS becoming a critical component of library operations and future strategy. Staffing, service, and security opportunities paired with support and maintenance challenges, enable the library to provide a unique critique and assessment of an AS/RS.

Resumen

It is widely accepted that firms can achieve effective inventory management with the right strategies. This study analyzed the inventory control strategies of small to medium-sized enterprises (SMEs) in Jamaica. The objectives of the study were to identify whether these companies used the “best practices” in inventory control, the effects of their strategies on business performance, and the factors that affected the development of their strategies. The study employed a methods triangulation approach that included case studies, interviews, questionnaires, and observation with a focus on twelve inventory-intensive SMEs in retail and manufacturing/distribution industries. The SMEs were found to use common inventory control strategies such as stock counts, Enterprise Resource Planning (ERP) systems, forecasting, and inventory classification.The findings of this study support institutional theory and isomorphism because it was discovered that due to external influences, firms studied within the same industry adopted similar strategies, and even in different industries, the ‘best practices’ in inventory control were the same. The drivers of this isomorphic organizational behavior were found to be costs, government regulations, and imitation of successful strategies in other companies. The SMEs surveyed were classified as semi-automated due to limited automation and confirmed success in their inventory management. The study validates the existence of institutionalism among SMEs in the retail as well as manufacturing/distribution industries in Jamaica. A broader scope examining larger firms and other industries would further identify isomorphic organizational behavior across the Jamaican business landscape. For future research, an investigation of financial performance and changes and adoption of new inventory control strategies of Jamaican SMEs is recommended to achieve a broad view of inventory management on the financial performance of Jamaican SMEs.

Resumen

The paper covers the application of Radio Frequency IDentification (RFID) technology in road traffic management with regard to vehicle identification. Various infrastructure configurations for Automated Vehicle Identification (AVI) have been presented, including configurations that can be used in urban traffic as part of the Smart City concept. In order to describe the behavior of multiple identifications of moving vehicles, an operation model of the dynamic identification using RFID is described. While it extends the definition of the correct work zone, this paper introduces the concept of dividing the zone into sections corresponding to so-called inventory rounds. The system state is described using a set of matrices in which unread, read, and lost transponders are recorded in subsequent rounds and sections. A simplified algorithm of the dynamic object identification system was also proposed. The results of the simulations and lab experiments show that the efficiency of mobile object identification is conditioned by the parameters of the communication protocol, the speed of movement, and the number of objects.

Resumen

In this paper, the authors the inventory control practices of a small-to-medium retailer to identify common challenges this type of organization experiences with respect to automated data capture (ADC) and the implementation of an enterprise wide information system. The study explores a single case of a hardware store in a regional town in New South Wales, Australia. Four semi-structured interviews were conducted with employees, focusing on issues related to inventory control including delivery discrepancies, checking and sorting of orders, locating stock and goods, loss prevention, customer purchasing and point of sale processing and replenishment. Flowcharts illustrate the current processes of the retailer with an understanding of how ADC technologies like bar code and radio-frequency identification (RFID) impact the retailer. The findings promote an evolutionary approach toward the use of automated data capture technology by adopting barcode technology and subsequently introducing the complementary RFID technology.

Resumen

Abstract The ubiquitous nature of inventory and its reliance on a reliable decision support system (DSS) is crucial for ensuring continuous availability of goods. The DSS needs to be designed in a manner that enables it to highlight its present status. Further, the DSS should be able to provide indications about subtle and large-scale variations that are likely to occur in the supply chain within the context of the decision-making framework and inventory management. However, while dealing with the parameters of the system, it is observed that its operations and mechanisms are surrounded by uncertain, imprecise, and vague environments. Fuzzy-based approaches are best suited for such situations; however, these require assistance from learning systems like artificial neural network (ANN) to facilitate automated decision support. When ANN and fuzzy are combined, the fuzzy neural system and the neuro-fuzzy system (NFS) are formulated. The model of the DSS reported here is based on a framework commonly known as adaptive neuro-fuzzy inference system (ANFIS), which is a version of NFS. The configured model has the advantages of both the ANN and fuzzy systems, and has been tested for the design of a DSS for use as part of inventory control. In this work, we report the design of an ANFIS-based DSS configured to work as DSS for inventory management. The system accepts demand as input and generates procurement, ordering, and holding cost to control production and supply. The system deals with a certain profitability rating required to quantify the changes in the input and is combined with the day-to-day inventory records and demand-available cycle. The effectiveness of the system has been checked in terms of number and types of membership used, accuracy generated, and computational efficiency accounted by the computation cycles required.

Resumen

Det har skett mycket de senaste åren inom tillverkningsindustrin. Kundanpassning med olika tillbehör och önskemål sätter press på företags förmåga att producera. En effektiv och noggrann hantering samt lagring av gods är en förutsättning för att förbli konkurrenskraftig. Det är väsentligt med lagerstyrning för kontroll av verksamhetens in- och utflöden i syfte att uppnå lönsamhet och hög kundnöjdhet. Hallberg-Rassy är skandinaviens största företag inom skeppsbyggnad som alltid levererat i tid. Med en ökad efterfråga och hantering av gods är lagerstyrningen viktig för att bevara kvaliteten. Företaget har uppmärksammat en misshantering av artiklar i främst höglagret som är i behov av ett förbättringsarbete. Företaget har ett stort centrallager som styrs av affärssystemet Navision. Problemet är att det befintliga affärssystemet inte kan utnyttjas till samtliga lager i verksamheten. Detta för att affärssystemet anpassats för mycket till centrallagret vilket resulterar i att systemets modul inte kan appliceras till företagets höglager. I dagsläget styrs höglagret av ett manuellt system i form av pärmar, där hanteringen leder till missvisande lagersaldon. Vi har med intervjuer och observationer av företaget samt framtagning av relevant teori, tagit reda på vilka faktorer som är anledningen till att manuella lagerrutiner bibehållas. Även vilka åtgärder som ska vidtas för att integrera manuella lagerrutiner i ett modernt lagerstyrningssystem. Men också undersökt vilka komplikationer en sådan övergång medför. Vi kom fram till att Hallberg-Rassy är kvar i manuella lagerrutiner för att integreringen i ett modernt lagerstyrningssystem medför stora kostnader med motstånd och rädsla från arbetarna. Denna integrering kan även medföra eventuella risker för en bristande kunskap av den nya modulen i affärssystemet. Detta sätter krav på utbildning för att upprätthålla hög arbetsmoral som främjar rätt indata till den nya modulen i affärssystemet.
A lot has happened in recent years in the manufacturing industry. Customization with different accessories and wishes puts pressure on companies' ability to produce. Efficient and accurate handling and storage of goods is a prerequisite for staying competitive. It is essential to have inventory management for control of the company's inputs and outflows in order to achieve profitability and high customer satisfaction. Hallberg-Rassy is Scandinavia's largest shipbuilding company that always delivers on time. With increased demand and handling of goods, inventory management is important in order to preserve quality. The company has a large central warehouse that is controlled by the business system Navision, but the problem is that the existing business system cannot be used for all the warehouses in the business. The business system has been adapted too much to the central warehouse, which means that the system cannot be applied to the company's other warehouse. Today is the other warehouse controlled by a manual system in the form of binders, where the handling entails a misleading stock balance. With interviews and observations of the company as well as the development of relevant theory, we’ve found out which factors that are the reasons manual inventory routines are retained. Also, which approach should be taken to integrate manual warehouse routines into a modern warehouse management system. We also investigated the complications of such a transition result. We concluded that Hallberg-Rassy remain the manual storage routines because integration to a modern warehouse management system causes high costs with resistance and fear from the workers. This integration can also pose potential risks for lack of knowledge of the new module in the business system. This requires training to maintain a high work ethic that promotes the right input to the new module in the business system.

Resumen

Automatic identification system is a prominent technology used in warehouses to give managers real time information of their products and assistance to warehouse employees in keeping an accurate inventory record. This kind of assistance is needed as an inaccurate inventory leads to profit loss due to misplacement or other mistakes. This project cooperated with an organization called Stora Enso specifically one of their forest nursery to find a solution to improve their inventory management system. Their current inventory system is a manual process which leads to mistakes occurring that affects the inventory accuracy. This thesis project evaluates automatic identification systems to observe if the technology is a possible solution and aims to answer the research question ”What are the significant impacts an automatic identification system has on an inventory management system?”. From the automatic identification evaluation one system is picked for further evaluation and due to its advantages radio frequency identification (RFID) is picked. To evaluate RFID in a warehouse setting a discrete-event simulation was created that simulates the forest nursery’s warehouse. The simulation is then used to evaluate the impact of different RFID implementations and their respective cost. The simulation results show that just a simple RFID implementation can improve inventory accuracy and remove some of the mistakes a manual system has with a relatively low direct cost. It also shows that a full RFID implementation that gives full visibility of a warehouse can almost remove inventory mistakes however the cost analysis shows that it requires a large investment.

Resumen

This bachelor thesis is about a stochastic inventory theory and how changes in different parameters affect the cost system. The inventory is based on a stochastic version of an economic quantity order (EOQ) model with planned shortages. For the deterministic EOQ-model with planned shortages there is a convenient formula for optimal order quantity $Q$ minimizing the cost per time unit. For the stochastic version an ($R$,$Q$)-policy is applied where $R$ is a reorder point such that if the inventory level is below $R$ and order is sent and the ordered products arrive after a lead time $L$. Since a formula for the stochastic inventory is not known, optimal choice of $Q$ is numerically obtained by simulations and compared with the optimal $Q$ for the deterministic EOQ with planned shortages. The demand is for simplicity described by a Poisson process. Since having a stochastic inventory model the basic mathematical EOQ formula is inadequate and is replaced with an approximate EOQ formula with planned shortages. By the simulations the accuracy of the EOQ model with planned shortages approximation is investigated and optimal values for some of the parameters are obtained.

This thesis documents a study carried out at the Novartis Institutes for BioMedical Research (NIBR) in Cambridge, MA. The study focused on the development of inventory management processes for laboratory consumables. The pharmaceutical R&D process is characterized by a dynamic project portfolio, which results in a great diversity of stock-keeping-units, low repeat order rates and high variability in consumption rates. These factors create significant challenges for the design of inventory management processes. We first present an assessment and diagnosis of the current state of inventory management at NIBR, using data gathered from various NIBR sites as well as other companies. We discuss underlying drivers that influence current behavior, and identify opportunities for improvement. We then develop alternative models for inventory management and compare these models along several dimensions such as stock room location & control, inventory ownership and replenishment options. We recommend the use of consolidated department level stock rooms as the most suitable option for NIBR. Detailed implementation plans are then developed and validated through a case study. We present key findings and recommendations for implementation, and discuss opportunities for future projects.

The purpose of this research was to determine inventory strategies for externally sourced medical devices. In the medical device industry, the desire for high levels of customer service often results in less than optimal inventory levels. In this study, we analyzed the details of the current inventory model utilized by the medical device company. In assigning appropriate inventory levels, we determined that key inputs were not regarded. When evaluating inventory levels, it was determined that pipeline inventory should be removed from the target on hand inventory levels if inventory ownership occurs upon receipt. When calculating safety stock, we determined that supply variability should be incorporated into the safety stock formula and extra buffers currently in place should be removed. In addition, a more robust measure of demand variability such as the Root Mean Squared Error (RMSE) or the Mean Absolute Percent Error (MAPE) should be incorporated into the formula instead of the use of the maximum of standard deviation of demand and standard deviation of forecast. Also, a gap was identified between the customer service safety factor used in the safety stock formula and the measurement of customer service by the company. Following the analysis of the current inventory modeling approach, we segmented the medical device SKU's based on key factors that drive inventory: demand, lead time, criticality and customer service. We also redefined the model used to determine slow moving inventory levels by incorporating the lead time of the part in setting cycle and safety stock levels and simulating the results to validate the relationships between the various inventory drivers. The application of the methodologies, concepts and findings in this research covering externally sourced medical devices can be extended to other subsidiaries and other industries.

Resumen

Thesis (Ph. D.)--Massachusetts Institute of Technology, Sloan School of Management, 2002.
Includes bibliographical references (p. 123-126).
We present a new methodology for analyzing multi-echelon inventory systems. The methodology relies on decomposing complicated multi-echelon inventory control problems into much smaller and managable subproblems, whose solutions in turn help us either characterize the structure of optimal policies for the corresponding overall problems and/or to compute optimal policies efficiently. We analyze four multi-echelon systems through this perspective. The first system is a serial system with stochastic leadtimes and Markov modulated demand. Here, the methodology amounts to focusing on a single unit as it travels through the supply chain and showing that the original problem is simply a series of single unit problems that are essentially decoupled. We are able to show that state dependent echelon base stock policies are optimal in this setting, both in finite and infinite horizon. A serial system with expediting options is analyzed next. A stage is not restricted to order items from the next upstream stage but can place orders at stages further upstream in the supply chain, by incurring certain extra costs. We show that given a restriction on the expediting cost structure that we call supermodularity, the system decomposes into single unit subproblems. We characterize the structure of optimal policies as extended echelon base stock policies, which is a generalization of echelon base stock policies. Next we study a serial system with batch size constraints. We show that the problem can be decomposed into subproblems, each of which has a single batch. We then show that (R, nQ) policies are optimal for this problem, which can be interpreted as echelon base stock policies that incorporate the batch size restrictions.
(cont.) In addition to providing a simple proof technique, the new approach gives rise to efficient algorithms for the calculation of the policy parameters, for all the systems described above. Finally we analyze an assembly system with stochastic leadtimes. We show that the problem can be decomposed into a series of subproblems, each with a single kit of parts. This enhances our understanding about optimal policies in this setting and we develop a relatively efficient algorithm for the computation of optimal policies.

Resumen

Abstract The challenges presented in the current market environment demand operational efficiency with low risk tolerance. Maximizing uptime and reducing unplanned events is paramount to preserve revenue. Asset Lifecycle Management (ALCM) is a strategy built to capitalize on the use of data analytics, superior system integration, and comprehensive condition assessments. This strategy is intended to produce significant benefits and maximize shareholder return through the optimization of maintenance, operations, and inventory. Traditional schedules of maintaining equipment can be replaced with automated analytics enhanced by equipment design knowledge and historical data. Developing technology enables a cost-effective means of applying this capability. Monitoring equipment condition and advanced analysis of equipment data compared to design parameters and historical performance provides valuable insight into the actual usage and lifecycle of the equipment. Design life utilization (usage) of critical load path drilling equipment can be determined by comparing how much work the equipment has done to how much work it was designed to do. This paper explores new methods of analyzing operational and equipment data, enabling the creation of robust usage models. These models are compared with the analysis of vibration, oil, fatigue, dimensional, and other physical inspection data. This empowers a comprehensive usage and condition monitoring paradigm that is data driven. Case studies performed on multiple drilling rigs proves extremely low usage and supports the deferral of traditional 5-year overhauls on this equipment. Modeling of normal operations is also explored, and a hook load model is created. The statistical analysis available from this operating model is compared to historical operational and maintenance records and proves to track an actual failure, thus substantiating value for anomaly detection if used real-time.

Resumen

In Germany mobile units are used to treat and condition radioactive waste. On behalf of the relevant authorities TUV SUD Industrie Service GmbH evaluates their safety. In this paper we outline the general procedure we apply and point out typical results. Generally, a generic safety case evaluates the effects of incidents and accidents and its consequences for the workers and the public. Special care is necessary to define the radioactive inventory, the nuclide composition and the mobility of the radioactive substances. A systems analysis is carried out. Typical aspects to be considered are the handling procedures, the measurement devices and automatic actions. From the various possible malfunctions the critical ones have to be identified. Generally one or only a few scenarios have to be considered in detail.

Resumen

The Los Alamos National Laboratory (LANL) is one of two design laboratories in the United States Department of Energy’s weapons complex, with over 60 years of experience in handling radioactive materials, and, consequently, in managing radioactive waste. Actinide research and development is conducted at the Plutonium Facility, which has been in operation since 1978 and is the major source of radioactive waste at LANL. The Nuclear Materials Technology (NMT) Division is responsible for operating the Plutonium Facility and has a dedicated group of personnel who manage radioactive and hazardous waste, and address environmental regulations. The NMT Division also oversees analytical support operations in the Chemistry and Metallurgy Research Facility. Operations at these two nonreactor nuclear facilities generate a wide variety of waste that may be generally classified as sanitary, hazardous, radioactive, and mixed (both radioactive and hazardous). The expedient, cost-effective, and regulatory-compliant management of radioactive waste has been a challenging task, given the propensity for rapid change in the regulatory environment. One major asset is the availability of information on waste generation and characteristics in electronic form. To do so, the Waste Inventory Tracking system (WITS) was developed 6 years ago to collect and store this information. To record waste information in the field, technicians use handheld Palm Pilots®. These units are then docked with personal computers to transfer the data to WITS. The primary use of WITS is the automated generation of waste package data reports, which are used to demonstrate compliance with waste acceptance criteria and gain acceptance for waste disposal. The WITS data are also used to evaluate various aspects of waste generation and handling, and to track performance indicators. The WITS is a fundamental part of waste management in the NMT Division.

Resumen

Decontamination prior to decommissioning and dismantling is an internationally accepted approach. Not only does it provide for minimization of personnel dose exposure but also maximization of the material volume available for free release. Since easier dismantling techniques in lower dose areas can be applied, the licensing process is facilitated and the scheduling and budgeting effort is more reliable. The most internationally accepted approach for decontamination prior to decommissioning projects is the Full System Decontamination (FSD). FSD is defined as the chemical decontamination of the primary cooling circuit, in conjunction with the main auxiliary systems. AREVA has long-term experience with Full System Decontamination for return to service of operating nuclear power plants as well as for decommissioning after shutdown. Since 1976, AREVA has performed over 500 decontamination applications and from 1986 on, decontaminations prior to decommissioning projects which comprise virtually all nuclear power plant (NPP) designs and plant conditions: • NPP designs: HPWR, PWR, and BWR by AREVA, Westinghouse, ABB and GE; • Decontaminations performed shortly after final shutdown or several years later, and even after re-opening safe enclosure; • High alpha inventory and or low gamma/alpha ratio; • Main coolant chemistry (e.g. with and without Zn injection during operation). Fifteen decontaminations prior to decommissioning projects have been performed successfully to date. The lessons learned of each project were consequently implemented for the next project. AREVA NP has developed a fully comprehensive approach for decontamination based on the CORD® (Chemical Oxidation Reduction Decontamination) Family, applied using the in-house designed decontamination equipment AMDA® (Automatic Modular Decontamination Appliance). The Decontamination Concept for Decommissioning (DCD) will be outlined in this paper. Based on highlights of previous FSDs performed prior to decommissioning the AREVA concept for FSD and DCD will be outlined: • Application window; • Decontamination area; • Waste considerations; • Positive results for subsequent decommissioning and dismantling activities.

Decontamination prior to Decommissioning and Dismantlement is imperative. Not only does it provide for minimization of personnel dose exposure but also maximization of the material volume available for free release.

The most internationally accepted approach for Decontamination prior to Decommissioning projects is the Full System Decontamination (FSD). FSD is defined as the chemical decontamination of the primary cooling circuit, in conjunction with the main auxiliary systems.

Fifteen Decontaminations prior to Decommissioning Projects have been performed successfully to date and the sixteenth FSD is now in the detailed engineering phase and is scheduled to commence late 2010. AREVA NP has developed a fully comprehensive approach for decontamination based on the CORD® (Chemical Oxidation Reduction Decontamination) Family, applied using the in-house designed decontamination equipment AMDA™ (Automatic Modular Decontamination Appliance). Based on the vast experience of AREVA NP in the field of decontamination, the Decontamination Concept for Decommissioning was developed. This concept ensures that the decontamination is tailored to the given boundaries and desired goals to ensure the best results with the lowest waste generation. This includes lower source term by oxide film, thus corrosion product, removal; controlled base metal attack to remove embedded activity; increased gamma/alpha ratios; and alpha contamination removal. This paper will describe the AREVA NP Decontamination Concept for Decommissioning (DCD) and present highlights of previous FSDs performed prior to decommissioning using the CORD/AMDA technology.

Resumen

Recent advances in visual sensing technology have gained much attention in the field of bridge inspection and management. Coupled with advanced robotic systems, state-of-the-art visual sensors can be used to obtain accurate documentation of bridges without the need for any special equipment or traffic closure. The captured visual sensor data can be post-processed to gather meaningful information for the bridge structures and hence to support bridge inspection and management. However, state-of-the-practice data postprocessing approaches require substantial manual operations, which can be time-consuming and expensive. The main objective of this study is to develop methods and algorithms to automate the post-processing of the visual sensor data towards the extraction of three main categories of information: 1) object information such as object identity, shapes, and spatial relationships - a novel heuristic-based method is proposed to automate the detection and recognition of main structural elements of steel girder bridges in both terrestrial and unmanned aerial vehicle (UAV)-based laser scanning data. Domain knowledge on the geometric and topological constraints of the structural elements is modeled and utilized as heuristics to guide the search as well as to reject erroneous detection results. 2) structural damage information, such as damage locations and quantities - to support the assessment of damage associated with small deformations, an advanced crack assessment method is proposed to enable automated detection and quantification of concrete cracks in critical structural elements based on UAV-based visual sensor data. In terms of damage associated with large deformations, based on the surface normal-based method proposed in Guldur et al. (2014), a new algorithm is developed to enhance the robustness of damage assessment for structural elements with curved surfaces. 3) three-dimensional volumetric models - the object information extracted from the laser scanning data is exploited to create a complete geometric representation for each structural element. In addition, mesh generation algorithms are developed to automatically convert the geometric representations into conformal all-hexahedron finite element meshes, which can be finally assembled to create a finite element model of the entire bridge. To validate the effectiveness of the developed methods and algorithms, several field data collections have been conducted to collect both the visual sensor data and the physical measurements from experimental specimens and in-service bridges. The data were collected using both terrestrial laser scanners combined with images, and laser scanners and cameras mounted to unmanned aerial vehicles.

Resumen

This study was conducted to inventory, classify, and map soils and vegetation within the ecosystems of Katmai National Park and Preserve (KATM) using an ecological land survey (ELS) approach. The ecosystem classes identified in the ELS effort were mapped across the park, using an archive of Geo-graphic Information System (GIS) and Remote Sensing (RS) datasets pertaining to land cover, topography, surficial geology, and glacial history. The description and mapping of the landform-vegetation-soil relationships identified in the ELS work provides tools to support the design and implementation of future field- and RS-based studies, facilitates further analysis and contextualization of existing data, and will help inform natural resource management decisions. We collected information on the geomorphic, topographic, hydrologic, pedologic, and vegetation characteristics of ecosystems using a dataset of 724 field plots, of which 407 were sampled by ABR, Inc.—Environmental Research and Services (ABR) staff in 2016–2017, and 317 were from existing, ancillary datasets. ABR field plots were located along transects that were selected using a gradient-direct sampling scheme (Austin and Heligers 1989) to collect data for the range of ecological conditions present within KATM, and to provide the data needed to interpret ecosystem and soils development. The field plot dataset encompassed all of the major environmental gradients and landscape histories present in KATM. Individual state-factors (e.g., soil pH, slope aspect) and other ecosystem components (e.g., geomorphic unit, vegetation species composition and structure) were measured or categorized using standard classification systems developed for Alaska. We described and analyzed the hierarchical relationships among the ecosystem components to classify 92 Plot Ecotypes (local-scale ecosystems) that best partitioned the variation in soils, vegetation, and disturbance properties observed at the field plots. From the 92 Plot Ecotypes, we developed classifications of Map Ecotypes and Disturbance Landscapes that could be mapped across the park. Additionally, using an existing surficial geology map for KATM, we developed a map of Generalized Soil Texture by aggregating similar surficial geology classes into a reduced set of classes representing the predominant soil textures in each. We then intersected the Ecotype map with the General-ized Soil Texture Map in a GIS and aggregated combinations of Map Ecotypes with similar soils to derive and map Soil Landscapes and Soil Great Groups. The classification of Great Groups captures information on the soil as a whole, as opposed to the subgroup classification which focuses on the properties of specific horizons (Soil Survey Staff 1999). Of the 724 plots included in the Ecotype analysis, sufficient soils data for classifying soil subgroups was available for 467 plots. Soils from 8 orders of soil taxonomy were encountered during the field sampling: Alfisols (<1% of the mapped area), Andisols (3%), Entisols (45%), Gelisols (<1%), Histosols (12%), Inceptisols (22%), Mollisols (<1%), and Spodosols (16%). Within these 8 Soil Orders, field plots corresponded to a total of 74 Soil Subgroups, the most common of which were Typic Cryaquents, Typic Cryorthents, Histic Cryaquepts, Vitrandic Cryorthents, and Typic Cryofluvents.

Protocol for Monitoring Fish Communities in Small Streams in the Heartland Inventory and Monitoring Network. National Park Service, abril de 2021. http://dx.doi.org/10.36967/nrr-2284726.

Texto completo

Resumen

Fish communities are an important component of aquatic systems and are good bioindicators of ecosystem health. Land use changes in the Midwest have caused sedimentation, erosion, and nutrient loading that degrades and fragments habitat and impairs water quality. Because most small wadeable streams in the Heartland Inventory and Monitoring Network (HTLN) have a relatively small area of their watersheds located within park boundaries, these streams are at risk of degradation due to adjacent land use practices and other anthropogenic disturbances. Shifts in the physical and chemical properties of aquatic systems have a dramatic effect on the biotic community. The federally endangered Topeka shiner (Notropis topeka) and other native fishes have declined in population size due to habitat degradation and fragmentation in Midwest streams. By protecting portions of streams on publicly owned lands, national parks may offer refuges for threatened or endangered species and species of conservation concern, as well as other native species. This protocol describes the background, history, justification, methodology, data analysis and data management for long-term fish community monitoring of wadeable streams within nine HTLN parks: Effigy Mounds National Monument (EFMO), George Washington Carver National Monument (GWCA), Herbert Hoover National Historic Site (HEHO), Homestead National Monument of America (HOME), Hot Springs National Park (HOSP), Pea Ridge National Military Park (PERI), Pipestone National Monument (PIPE), Tallgrass Prairie National Preserve (TAPR), and Wilson's Creek national Battlefield (WICR). The objectives of this protocol are to determine the status and long-term trends in fish richness, diversity, abundance, and community composition in small wadeable streams within these nine parks and correlate the long-term community data to overall water quality and habitat condition (DeBacker et al. 2005).

Resumen

The Heartland Inventory and Monitoring Network (HTLN) is a component of the National Park Service’s (NPS) strategy to improve park management through greater reliance on scientific information. The purposes of this program are to design and implement long-term ecological monitoring and provide information for park managers to evaluate the integrity of park ecosystems and better understand ecosystem processes. Concerns over declining surface water quality have led to the development of various monitoring approaches to assess stream water quality. Freshwater streams in network parks are threatened by numerous stressors, most of which originate outside park boundaries. Stream condition and ecosystem health are dependent on processes occurring in the entire watershed as well as riparian and floodplain areas; therefore, they cannot be manipulated independently of this interrelationship. Land use activities—such as timber management, landfills, grazing, confined animal feeding operations, urbanization, stream channelization, removal of riparian vegetation and gravel, and mineral and metals mining—threaten stream quality. Accordingly, the framework for this aquatic monitoring is directed towards maintaining the ecological integrity of the streams in those parks. Invertebrates are an important tool for understanding and detecting changes in ecosystem integrity, and they can be used to reflect cumulative impacts that cannot otherwise be detected through traditional water quality monitoring. The broad diversity of invertebrate species occurring in aquatic systems similarly demonstrates a broad range of responses to different environmental stressors. Benthic invertebrates are sensitive to the wide variety of impacts that influence Ozark streams. Benthic invertebrate community structure can be quantified to reflect stream integrity in several ways, including the absence of pollution sensitive taxa, dominance by a particular taxon combined with low overall taxa richness, or appreciable shifts in community composition relative to reference condition. Furthermore, changes in the diversity and community structure of benthic invertebrates are relatively simple to communicate to resource managers and the public. To assess the natural and anthropo-genic processes influencing invertebrate communities, this protocol has been designed to incorporate the spatial relationship of benthic invertebrates with their local habitat including substrate size and embeddedness, and water quality parameters (temperature, dissolved oxygen, pH, specific conductance, and turbidity). Rigid quality control and quality assurance are used to ensure maximum data integrity. Detailed standard operating procedures (SOPs) and supporting information are associated with this protocol.

Resumen

A lack or limited availability for parking may have multiple consequences, not the least of which is driver frustration, congestion, and air pollution. However, there is a greater problem that is not widely recognized by the public, namely the negative effect on the use of transit systems due to insufficient parking spaces close to key transit stations. Automated parking management systems, which have been successfully deployed in several European and Japanese cities, can manage parking needs at transit stations more effectively than other alternatives. Numerous studies have confirmed that quick and convenient automobile access to park-and-ride lots can be essential to making public transit competitive with the automobile in suburban areas. Automated parking systems use a robotic platform that carries each vehicle to one of the locations in a custom designed structure. Each location is designed compactly so that considerably more vehicles can be parked in the automated garages than the traditional parking lots. Central to the design of these systems are three key technologies, namely: 1. Mechanical design and the operation of vehicle transfer, i.e., the robotic platform 2. Structural and architectural requirements to meet safety and earthquake standards, among other design imperatives, 3. Automation and intelligent control issues as related to the overall operation and system engineering. This article concerns the first technology, and more specifically the design of the robotic platform for vehicle transfers. We will outline the overall design of the robot and the shuttle, followed by a description of the prototype that was developed in our laboratories. Subsequently, performance related issues and scalability of the current design will be analyzed.

Resumen

Switzerland’s energy grids are reliable and stable – but they are facing new challenges. These include the fact that the new renewable energy sources, namely photovoltaic systems and wind farms, only produce electricity on an irregular basis. Greater flexibility is therefore required in the energy grid: with new storage solutions for electricity and heat on the supply side and automated load management on the demand side. The potential synergies between the various energy sources must also be exploited.

Resumen

In 2015, the Natural Sounds and Night Skies Division (NSNSD) received a request to collect baseline acoustical data at Mesa Verde National Park (MEVE). Between July and August 2015, as well as February and March 2016, three acoustical monitoring systems were deployed throughout the park, however one site (MEVE002) stopped recording after a couple days during the summer due to wildlife interference. The goal of the study was to establish a baseline soundscape inventory of backcountry and frontcountry sites within the park. This inventory will be used to establish indicators and thresholds of soundscape quality that will support the park and NSNSD in developing a comprehensive approach to protecting the acoustic environment through soundscape management planning. Additionally, results of this study will help the park identify major sources of noise within the park, as well as provide a baseline understanding of the acoustical environment as a whole for use in potential future comparative studies. In this deployment, sound pressure level (SPL) was measured continuously every second by a calibrated sound level meter. Other equipment included an anemometer to collect wind speed and a digital audio recorder collecting continuous recordings to document sound sources. In this document, “sound pressure level” refers to broadband (12.5 Hz–20 kHz), A-weighted, 1-second time averaged sound level (LAeq, 1s), and hereafter referred to as “sound level.” Sound levels are measured on a logarithmic scale relative to the reference sound pressure for atmospheric sources, 20 μPa. The logarithmic scale is a useful way to express the wide range of sound pressures perceived by the human ear. Sound levels are reported in decibels (dB). A-weighting is applied to sound levels in order to account for the response of the human ear (Harris, 1998). To approximate human hearing sensitivity, A-weighting discounts sounds below 1 kHz and above 6 kHz. Trained technicians calculated time audible metrics after monitoring was complete. See Methods section for protocol details, equipment specifications, and metric calculations. Median existing (LA50) and natural ambient (LAnat) metrics are also reported for daytime (7:00–19:00) and nighttime (19:00–7:00). Prominent noise sources at the two backcountry sites (MEVE001 and MEVE002) included vehicles and aircraft, while building and vehicle predominated at the frontcountry site (MEVE003). Table 1 displays time audible values for each of these noise sources during the monitoring period, as well as ambient sound levels. In determining the current conditions of an acoustical environment, it is informative to examine how often sound levels exceed certain values. Table 2 reports the percent of time that measured levels at the three monitoring locations were above four key values.
