Abstract:

Purpose The purpose of this paper is cost optimization of project schedules under constrained resources and alternative production processes (APPs). Design/methodology/approach The model contains a cost objective function, generalized precedence relationship constraints, activity duration and start time constraints, lag/lead time constraints, execution mode (EM) constraints, project duration constraints, working time unit assignment constraints and resource constraints. The mixed-integer nonlinear programming (MINLP) superstructure of discrete solutions covers time–cost–resource options related to various EMs for project activities as well as variants for production process implementation. Findings The proposed model provides the exact optimal output data for project management, such as network diagrams, Gantt charts, histograms and S-curves. In contrast to classic scheduling approaches, here the optimal project structure is obtained as a model-endogenous decision. The project planner is thus enabled to achieve optimization of the production process simultaneously with resource-constrained scheduling of activities in discrete time units and at a minimum total cost. Practical implications A set of application examples are addressed on an actual construction project to display the advantages of proposed model. Originality/value The unique value this paper contributes to the body of knowledge reflects through the proposed MINLP model, which is capable of performing the exact cost optimization of production process (where presence and number of activities including their mutual relations are dealt as feasible alternatives, meaning not as fixed parameters) simultaneously with the associated resource-constrained project scheduling, whereby that is achieved within a uniform procedure.

Abstract:

O desenvolvimento da indústria é dado por inovações, aplicação de técnicas de gestão e implementação de tecnologias. Ao atuar em busca de inovações as organizações encontram a necessidade de investir em pesquisa e desenvolvimento (P&D). As áreas de P&D são movimentadas através de pesquisas que buscam melhorias significativas nos processos, como também, a orientação para novas aplicações da tecnologia disponível na elaboração de projetos que venham impactar o mercado sob uma perspectiva funcional e diferente do que é apresentado até então. Ao pensar nisso é nítido que a gestão dos projetos desenvolvidos por uma empresa pode lhe proporcionar a liderança em seu mercado de atuação ou ser a fonte de prejuízos inestimáveis. A atuação do Engenheiro de Produção quanto a elaboração e gestão de projetos reside em garantir sucesso nos projetos. A aplicação de técnicas de gestão nos projetos permite o controle sobre as atividades do projeto atuando sob as adversidades encontradas no caminho. O presente estudo tem por objetivo demonstrar o funcionamento das técnicas de gestão de projeto sob a prática da elaboração de um projeto simples, utilizado didaticamente pelo corpo docente, promovendo a vivência dos dados levantados em sala de aula, separadas por fase de planejamento, controle e execução. Os dados foram comparados usando técnicas de gestão de projetos. Com o seguinte estudo foi possível compreender de maneira dinâmica o planejamento de um projeto e compará-lo à experiência prática, utilizando parâmetros levantados pelas ferramentas de gestão avaliando custos, riscos e prazos inerentes ao projeto. Pode-se concluir que as ferramentas de gestão de projetos foram aplicáveis, como também, puderam demonstrar a variação de um projeto em relação ao planejado, podendo assim os alunos gerenciarem projetos de forma prática e dinâmica.

Abstract:

Project is any work that has a beginning and ending, consisting of several jobs/activities that must be carried out in a certain order. Contractors typically use the Gantt Chart Method in scheduling home construction projects so that it is difficult to know the impact caused by the late completion of work on scheduling the entire project. The purpose of this study is to determine the time needed to complete two housing units using the Precedence Diagram Method and the Line of Balance Method. The data used in this research are the dependency relationship between activities, time schedule, cost analysis plan (RAB), and SNI unit price analysis. The analysis process carried out in this study is to calculate the time needed to complete two housing units using two methods, namely the Precedence Diagram Method and the Line of Balance method. The results of this study indicate the time needed to build two housing units using the Precedence Diagram Method 7 days faster than using the Line of Balance Method.

Abstract:

Low-carbon product design involves a redesign process that requires not only structural module modification, but more importantly, generating innovative principles to solve design contradictions. Such contradictions include when current design conditions cannot satisfy design requirements or there are antithetical design goals. On the other hand, configuration tasks in the reconfiguration process are interdependent, which requires a well-scheduled arrangement to reduce feedback information. This study proposes an effective configuration methodology for low-carbon design. Firstly, configuration tasks and configuration parameters are designated through quality characteristics, and the directed network along with the associated values of configuration tasks are transformed into the design structure matrix to construct the information flow diagram. Then, the Extenics-based problem-solving model is presented to address design contradictions: low-carbon incompatibility and antithetical problems are clarified and formulated with a basic-element model; extensible and conjugate analysis tools are used to identify problematic structures and provide feasible measures; the Gantt chart of measures execution based on the information flow diagram is constructed to reduce feedback and generate robust schemes with strategy models. The methodology is applied to the vacuum pump low-carbon design, the results show that it effectively solves contradictions with innovative design schemes, and comparative analysis verifies the performance of Extenics.

Abstract:

The article considers the issues of presenting the results of simulation experiments with models based on Petri nets for a researcher. The need for a qualitative review of the applied methods for visualizing Petri nets of both the processes themselves and the modeling results has been identified and justified. An analysis of publications on the subject of Petri nets allowed us to conclude that the visualization of such models and the results of their modeling is a known weak point. It is this factor that significantly limits the use of Petri nets as a tool for solving practical problems. The characteristic features of the calendar planning problem and the applied forms of presenting the results of its solution are analyzed. Based on the analysis of literary sources and empirical data, the feasibility of solving the planning problem on the basis of preliminary simulation modeling by Petri nets is substantiated. The method of automatic formation of Gantt diagrams is formalized. The mechanisms for identifying the state of system resources by transitions of the network model are determined. In developing the approach, the attributes and characteristics of its elements already existing in the simulation network model were used to the maximum. An example of using the proposed approach based on the model of a typical robotic technological complex is given. According to the results of the experiment, it was revealed that the software implementation of the described formal rules does not significantly affect the speed of model simulation for the presented robotic system. The proposed approach has the same versatility as the mathematical apparatus used timed Petri nets. This allows us to describe the results of modeling systems and processes of different types, for example, transport or information. An important advantage of the implemented mechanism for the connection of Petri nets and Gantt diagrams is the transfer of the dynamic nature of networks to the process analysis procedures based on diagrams. There is also the possibility of introducing stochastic characteristics of the processes both in the simulation model and in the generated Gantt diagram. The direction of further research on the topic of the article may be the application and corresponding refinement of the obtained formal rules for simulating a network with identification of resources for other classes of Petri nets often used in practice, for example, color Petri nets or E-nets.

Abstract:

Linear diagrams have been shown to compare favourably to better known forms of set visualization, such as Venn and Euler diagrams, in supporting non-interactive assessment of set relationships. Recent studies that compared several variants of linear diagrams have demonstrated that users perform best at tasks involving identification of intersections, disjointness and subsets when using a horizontally drawn linear diagram with thin lines representing sets and employing vertical lines as guide lines. The essential visual task the user needs to perform in order to interpret this kind of diagram is vertical alignment of parallel lines and detection of overlaps. Space-filling mosaic diagrams which support this same visual task have been used in other applications, such as the visualization of schedules of activities, where they have been shown to be superior to linear Gantt charts. In this article, we present an experimental comparison of linear and mosaic diagrams for visualization of set relationships, in terms of accuracy, time-to-answer and subjective ratings of perceived task difficulty. The findings show that the two visualizations are largely similar with respect to these measures, suggesting that the choice of one or the other may be solely guided by other visual design considerations. Mosaic diagrams might be more suitable, for instance, in cases where miniature diagrams representing overviews of relations in different collections of sets are required, such as in small-multiples displays.

Abstract:

Abstract. Marine organic aerosol emissions have been implemented and evaluated within the National Center of Atmospheric Research (NCAR)'s Community Atmosphere Model (CAM5) with the Pacific Northwest National Laboratory's 7-mode Modal Aerosol Module (MAM-7). Emissions of marine primary organic aerosols (POA), phytoplankton-produced isoprene- and monoterpenes-derived secondary organic aerosols (SOA) and methane sulfonate (MS−) are shown to affect surface concentrations of organic aerosols in remote marine regions. Global emissions of submicron marine POA is estimated to be 7.9 and 9.4 Tg yr−1, for the Gantt et al. (2011) and Vignati et al. (2010) emission parameterizations, respectively. Marine sources of SOA and particulate MS− (containing both sulfur and carbon atoms) contribute an additional 0.2 and 5.1 Tg yr−1, respectively. Widespread areas over productive waters of the Northern Atlantic, Northern Pacific, and the Southern Ocean show marine-source submicron organic aerosol surface concentrations of 100 ng m−3, with values up to 400 ng m−3 over biologically productive areas. Comparison of long-term surface observations of water insoluble organic matter (WIOM) with POA concentrations from the two emission parameterizations shows that both Gantt et al. (2011) and Vignati et al. (2010) formulations are able to capture the magnitude of marine organic aerosol concentrations, with the Gantt et al. (2011) parameterization attaining better seasonality. Model simulations show that the mixing state of the marine POA can impact the surface number concentration of cloud condensation nuclei (CCN). The largest increases (up to 20 %) in CCN (at a supersaturation (S) of 0.2 %) number concentration are obtained over biologically productive ocean waters when marine organic aerosol is assumed to be externally mixed with sea-salt. Assuming marine organics are internally-mixed with sea-salt provides diverse results with increase and decrease in the concentration of CCN over different parts of the ocean. The sign of the CCN change due to the addition of marine organics to sea-salt aerosol is determined by the relative significance of the increase in mean modal diameter due to addition of mass, and the decrease in particle hygroscopicity due to compositional changes in marine aerosol. Based on emerging evidence for increased CCN concentration over biologically active surface ocean areas/periods, our study suggests that treatment of sea spray in global climate models (GCMs) as an internal mixture of marine organic aerosols and sea-salt will likely lead to an underestimation in CCN number concentration.

Abstract:

To optimize the process of pharmaceutical development, it is necessary to take into account the timeframes of the processes and to track all its key stages. To do this, it is necessary to create an algorithm for conducting research, taking into account the modern approach to pharmaceutical development the concept of Quality by Design. The aim of this work was to create an algorithm of actions in conducting research when developing a new drug that can be used in the production process. Flowcharts were used for depicting algorithms. To account the timeframes of the processes, a Gantt diagram was used. The process of pharmaceutical development when launching a new generic drug has been studied at an operating pharmaceutical company. An algorithm for the actions of staff involved in research is proposed The algorithm minds the concept of Quality by Design. A temporary Gannta scheme and a project manager's control card for the process of pharmaceutical development of a generic drug have been developed. Based on the results of the work, an algorithm of actions in conducting research when developing a new drug that can be used in the production process was proposed.

Abstract:

AbstractS-type stars are late-type giants enhanced with s-process elements originating either from nucleosynthesis during the Asymptotic Giant Branch (AGB) or from a pollution by a binary companion. The former are called intrinsic S stars, and the latter extrinsic S stars. The atmospheric parameters of S stars are more numerous than those of M-type giants (C/O ratio and s-process abundances affect the thermal structure and spectral synthesis), and hence they are more difficult to derive. Nevertheless, high-resolution spectroscopic data of S stars combined with the TGAS (Tycho-Gaia Astrometric solution) parallaxes were used to derive effective temperatures, surface gravities, and luminosities. These parameters allow to locate the intrinsic and extrinsic S stars in the Hertzsprung-Russell diagram.

Abstract:

Summary Objectives: Adequate instruments are needed to reflect the complexity of routine cancer registry operations properly in a business model. The activity diagram is a key instrument of the Unified Modeling Language (UML) for the modeling of business processes. The authors aim to improve descriptions of processes in cancer registration, as well as in other public health domains, through the enhancements of an activity diagram notation within the standard semantics of UML. Methods: The authors introduced the practical approach to enhance a conventional UML activity diagram, complementing it with the following business process concepts: timeline, duration for individual activities, responsibilities for individual activities within swimlanes, and descriptive text. Results: The authors used an enhanced activity diagram for modeling surveillance processes in the cancer registration domain. Specific example illustrates the use of an enhanced activity diagram to visualize a process of linking cancer registry records with external mortality files. Conclusions: Enhanced activity diagram allows for the addition of more business concepts to a single diagram and can improve descriptions of processes in cancer registration, as well as in other domains. Additional features of an enhanced activity diagram allow to advance the visualization of cancer registration processes. That, in turn, promotes the clarification of issues related to the process timeline, responsibilities for particular operations, and collaborations among process participants. Our first experiences in a cancer registry best practices development workshop setting support the usefulness of such an approach.

Abstract:

Testing is the stage of software development used to determine whether a software is ready for release or not. In making test cases using reference activity diagrams and statechart diagrams, a help representation was made, ie State-Activity-Diagram (SAD). The generation of test cases using a reference between the statechart diagram and the status diagram is still inadequate because in the case of the test produced there is no test data. The selection of test data for many test cases will be tedious and time consuming. In this paper, it is proposed to generate test data automatically based on existing test cases. Test data created based on class diagrams, and data dictionaries. The test case data consists of inputs and results. First enter information about the functions involved in the test case into the SAD node so that the SAD-S Diagram is obtained. Second, after the process of making the test case is completed, the test data is made by looking at the data dictionary function so that the test data is formed.

Abstract:

Project schedule control is one of the important control goals in project management. It is an important measure to ensure that the project is completed safely, reasonable arrangements for the resources supply and saving cost. Any of the projects must be by means of scientific planning and control methods in order to achieve the desired goals. Deviation analysis is an ongoing work in the progress of project, how to determine the deviation of project timely and accurately, the method that used is crucial. This paper chose a highway construction project as research object, using the Inspection Acts include Gantt chart, S-shaped curve and Banana-shaped curve of schedule, and made the comparative analysis for project to identify deviations and take measures to adjust in order to ensure the project is completed on schedule.

Abstract:

We study the Hausdorff Voronoi diagram of a set S of polygonal objects in the plane, a generalization of Voronoi diagrams based on the maximum distance of a point from a polygon, and show that it is equivalent to the Voronoi diagram of S under the Hausdorff distance function. We investigate the structural and combinatorial properties of the Hausdorff Voronoi diagram and give a divide and conquer algorithm for the construction of this diagram that improves upon previous results. As a byproduct we introduce the Hausdorff hull, a structure that relates to the Hausdorff Voronoi diagram in the same way as a convex hull relates to the ordinary Voronoi diagram. The Hausdorff Voronoi diagram finds direct application in the problem of computing the critical area of a VLSI Layout, a measure reflecting the sensitivity of a VLSI design to random manufacturing defects, described in a companion paper.13

Abstract:

We study coupled channel effects upon isospin I=2 and I=0 ππ S-wave interaction. With introduction of the ππ→ρρ→ππ coupled channel box diagram contribution into ππ amplitude in addition to ρ and f2(1270) exchange, we reproduce the ππ I =2 S-wave and D-wave scattering phase shifts and inelasticities up to 2 GeV quite well in a K-matrix formalism. For I=0 case, the same ππ→ρρ→ππ box diagram is found to give the largest contribution for the inelasticity among all possible coupled channels including ππ→ωω→ππ, [Formula: see text]. We also show why the broad σ appears narrower in production processes than in ππ scattering process.

Vertical Sauver′s diagrams provide analogous information about specific alloys same as classical Sauver′s diagram, the Tamman′s diagram or cooling curve with the lever rule application. Particular animation programs like Macromedia Flash facilitate in construction of vertical diagrams and enable their fluent transformation depending on chemical constitution of alloys. Utilization of function masking enables monitoring of the phasic, structural and complex constitution of alloy in the course of different temperature at the same time. Unique structure description of the metal alloys extends knowledge in metallographic science.

Abstract:

Context. S stars are late-type giants that are transition objects between M-type stars and carbon stars on the asymptotic giant branch (AGB). They are classified into two types: intrinsic or extrinsic, based on the presence or absence of technetium (Tc). The Tc-rich or intrinsic S stars are thermally pulsing (TP-)AGB stars internally producing s-process elements (including Tc) that are brought to their surface via the third dredge-up (TDU). The Tc-poor or extrinsic S stars gained their s-process overabundances via the accretion of s-process-rich material from an AGB companion that has since turned into a dim white dwarf. Aims. Our goal is to investigate the evolutionary status of Tc-rich S stars by locating them in a Hertzsprung-Russell (HR) diagram using the results of Gaia Early Data Release 3 (EDR3). We combine the current sample of 13 Tc-rich stars with our previous studies of 10 Tc-rich stars to determine the observational onset of the TDU in the metallicity range [−0.7; 0]. We also compare our abundance determinations with dedicated AGB nucleosynthesis predictions. Methods. We derived the stellar parameters using an iterative tool that combines HERMES high-resolution spectra, accurate Gaia EDR3 parallaxes, stellar evolution models, and tailored MARCS model atmospheres for S-type stars. Using these stellar parameters, we determined the heavy-element abundances by line synthesis. Results. In the HR diagram, the intrinsic S stars are located at higher luminosities than the predicted onset of the TDU. These findings are consistent with Tc-rich S stars being genuine TP-AGB stars. The comparison of the derived s-process abundance profiles of our intrinsic S stars with the nucleosynthesis predictions provide an overall good agreement. Stars with highest [s/Fe] tend to have the highest C/O ratios.

Abstract:

As the only nonlinear component for symmetric cryptography, S-Box plays an important role. An S-Box may be vulnerable because of the existence of fixed point, reverse fixed point or short iteration cycles. To construct a keyed strong S-Box, first, a 2D enhanced quadratic map (EQM) was constructed, and its dynamic behaviors were analyzed through phase diagram, Lyapunov exponent, Kolmogorov entropy, bifurcation diagram and randomness testing. The results demonstrated that the state points of EQM have uniform distribution, ergodicity and better randomness. Then a keyed strong S-Box construction algorithm was designed based on EQM, and the fixed point, reverse fixed point, and short cycles were eliminated. Experimental results verified the algorithm’s feasibility and effectiveness.

Abstract:

The "Q-curves [Formula: see text] have long been observed and studied as the shadowy curves which appear illusively — not explicitly drawn — in the familiar orbit diagram of Myrberg's map fc(x) = x2 + c. We illustrate that Q-curves also appear implicitly, for a different reason, in a computer-drawn bifurcation diagram of x2 + c as well — by "bifurcation diagram" we mean the collection of all periodic points of fc (attracting, indifferent and repelling) — these collections form what we call "P-curves". We show Q-curves and P-curves intersect in one of two ways: At a superattracting periodic point on a P-curve, the infinite family of Q-curve s which intersect there are all tangent to the P-curve. At a Misiurewicz point, no tangencies occur at these intersections; the slope of the P-curve is the fixed point of a linear system whose iterates give the slopes of the Q-curves. We also introduce some new phenomena associated with c sin x illustrating briefly how its two different families of Q-curves interact with P-curves. Our algorithm for finding and plotting all periodic points (up to any reasonable period) in the bifurcation diagram is reviewed in an Appendix.

<p><strong>Abstract.</strong> The purpose of this contribution is to describe the use of the HBIM method for the management of the restoration building site applied to a historic building in the heart of the historic center of L'Aquila. The construction is located in a densely constructed area and it is characterized by a high spatial complexity with various types of limitations including: small external and internal spaces and interferences due to neighboring construction sites. The proposed method involves a particularly detailed organization of the construction site, simultaneously planning both the development of the working and the safety in order to have more transparency and more control of the information shared among stakeholders. This method consists in planning the Gantt diagram from general to detailed level, according to certain parameters that will be cross-examined and checked regurarly. A screening step has been carried out regarding the current situation, the proceedings to be undertaken and the stakeholders to be included. Thank to this, it has been possible to have automated processes to control not only geometrical interferences but also the ones related to the completion of the work in the interest of enhancing the risk management. Due to a 3D and 4D BIM modelling, there are been found advanced layouts and some timeliners that have allowed a rigourus control of the building process, particularly in the case of precise working and potencial changes that are common in building sites of this type.</p>

Abstract:

This paper proposes a method of developing ladder logic diagram for PLCs via S-method (a structured method of programming routines). From flexible manufacturing industry point of view, engineers can easily understand the operation of the complicated system and have better control on industrial automation system by applying S-method. By practicing this, highly dependent on vendor for operating the system also can be eliminated. This paper describes detailed steps of the method that converts from description of the system to a ladder logic diagram involving a series of systematic steps. A case study on pick and place section, the KUKA system which is implementing the S-method is discussed in paper.

Abstract:

Abstract The phase diagram of the quasiternary system (Snt Pb1-k)(S,Te1-l) for 900 K is determined by X-ray diffraction and by electron microprobe analysis. Moreover, the free enthalpy faces g(k, I) for the phases with cubic rocksalt structure (cub) or with the orthorhombic SnS structure (orh) are calculated from the interaction parameters and from the orh → cub transition data of the 4 quasibinary subsystems. The interaction parameters are also used to calculate the termodynamic factor for interdiffusion along quasibinary sections through the phase square and to calculate the energies of four-particle clusters. By application of the cluster model one obtains information on the local environment of the mixing particles and on the cluster processes that have effect upon interdiffusion
