Full textAbstract:
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.

Full textAbstract:
This research is focused on the technology transfer process in the automobile industry using project management tools. The aim of this research is the development of a technology-transfer model using Gantt charts and Critical Path Analysis flow diagrams to achieve a sustainable planning process in the global environment. To achieve this goal, the authors use Gantt charts and Critical Path Analysis flow diagrams. The hypothesis and three research questions are presented, which suggest a relationship between project management tools and the sustainable planning process of technology transfer. During the research, we use the case study of the Korean automobile industry as an excellent example of the technology-transfer process in global markets. A single project of technology transfer is discussed: the technology knowledge transfer from Korean headquarters to a Russian manufacturing subsidiary (Hyundai Motor Corporation). Quantitative data were collected through the open resources of the corporation; the qualitative data were analyzed through a case study and model parameter evaluation. The significant result that the combination of Gantt Charts and Critical Path Analysis flow diagrams methods improves the planning process for technology-transfer projects was found in this survey. It is noticed that (a) it is useful to apply project-management tools for technology transferring models; (b) Gantt Charts and Critical Path Analysis flow diagrams have a sustainable impact on technology transfer projects; and (c) critical paths and operational reserves in network diagrams help to optimize the planning process for technology transfer.

Full textAbstract:
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.

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.

Full textAbstract:
In contemporary Project Management literature and practice, it is possible to distinguish two paradigms: the algorithmic-rational paradigm and the relational paradigm. The algorithmic-rational paradigm is characterized by a sequence of programming methodologies that constitute the classic corpus of knowledge on Project Management (WBS, CPM, PERT, Gantt diagrams). Following the diffusion of Agile methods, dissatisfaction with the algorithmic-rational paradigm has spread and a Visual Planning approach, based on the decentralization of planning and control and the abandonment of algorithmic techniques (such as CPM and Gantt diagrams) in favour of simpler, visual and physical tools, has become increasingly established. Visual Planning is the concrete manifestation of a relational project management paradigm. In this work, through an analysis of the key practices characterizing Visual Planning, we have identified the five fundamental principles that define this approach to project management. Then, to structure and guide the choice of a software application that can support Visual Planning, we have (1) identified several features which allow distinguishing one software from another, and (2) created a correlation matrix between the core principles of Visual Planning and the software features. Through this matrix, it is possible to evaluate and measure the adherence of project management software applications to the logic and practices of physical Visual Planning.

Project management skills such as WBS, Gantt Chart and PERT have been applied in many fields, but system analysts preferred UML to project tools. This article recommend transformation rules from project items into objects and project charts into UML diagrams, to model all project items and processes by using UML. Therefore, UML can be applied not only to system analysis and design, but also to entire project processes. Stakeholders in a project can rethink the project in terms of object orientation and communicate with system developers using the same tool as UML.

Full textAbstract:
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.

An analysis model has been developed that includes the main components of the Gantt chart and Pareto diagrams and the sensitivity analysis of the project. An example of the application of this model for the integration of the 1C: Enterprise system as a data source into a decision support system is given. When analyzing the sensitivity of the project, the task is to select and quickly calculate the time and sequence of actions that affect the final result. A sensitivity chart of the project is proposed, which is based on calculating the percentage of deviation of the indicator from the planned by the project and serves to control and redistribute the employees released as a result of the introduction of information technologies.

Hoy en día en la búsqueda de la optimización del tiempo resulta imprescindible en cualquier empresa, administrarlo de forma eficaz permite reducir costes, aumentar la satisfacción de los clientes, mejorar los resultados con menos esfuerzos…. Los diagramas de Gantt son sin duda de gran ayuda en esta labor, existiendo herramientas informáticas que permiten no solo su representación gráfica de forma muy sencilla, sino la explotación de los datos que se desprenden de la relación existente entre el final e inicio de una actividad, con el final e inicio del resto de actividades. En el presente artículo se propone, en base a la experiencia, una metodología de trabajo para controlar el tiempo de un conjunto de actividades, así como el planteamiento y la solución al problema de la Doble Ligadura, que a buen seguro, habrá dado más de un quebradero de cabeza a muchos técnicos.Palabras claves: gestión del tiempo, doble ligadura, camino crítico, ligadura crítica, Gantt.Time Managment: Solution to the problem of double constraintAbstract: Many technicians, in their professional activity, need to control the execution deadline of all the activities or components that make up projects, works, and processes. In an attempt to address that need, and even before the existence of computers, Henry L. Grantt proposed a methodology for the graphic representation of those activities, so as to give an approximate idea of who they each interacted with the others, as well as each of the activities’ impact on the total execution period. Computer science has allowed the creation of various tools that lead to easily and intuitively elaborate Grantt diagrams, and to use the information about each activity’s duration and the relation that exists between the start and end of each activity with the others. The Critical Path analysis allows the classification of activities as critical and non-critical. A delay in execution of the former will result in a delay on the total execution period, whereas non-critical activities function within a margin in such a way that a delay in completion will have little to no impact on the total execution period. Among all of the computing tools in existence on the market for the generation of Grantt diagrams, Microsoft Project is perhaps the most widely used by technicians. It basically requires two inputs: the estimated duration of each of the activities making up a project, and the existing relations between their start and end. Said relations require conditioning through Restraints, the end or start of an activity with the start or end of another. These restraints imply the joining of two activities under the condition that the start or end of one will only occur after a determined period of time from the start or end of the other. Microsoft Project presents the important restriction of not allowing to establish more than one restraint between two activities; meaning, if for instance, the start of one activities is conditioned by the start of another, there will not be any more relations between those two activities, such as the end of said activities, in which case incorrect or hardly comprehensive data may be constructed. The above mentioned restriction is not a minor problem, for if analyzed correctly, when the start of one activity conditions the start of another, which frequently occurs, the ends of both activities will likely also be similarly related. For example, a facade closing evidently cannot be started until part of the structure has been completed, but it is not less true that the closing cannot be finished until after the total execution of the structure. In this article, I will attempt to explain in simple but rigorous manner the fundamental elements of the technical programming of a project. A work methodology will be proposed to ease the work of the technicians, and I will try to offer a solution to the problem of the Double Restraint between activities, which has certainly been making it difficult for the many technicians who use Microsoft Project on a daily basis.Keywords: Time Management, Double Constraint, Critical Path, Critical Constraint, Gantt

<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>

Full textAbstract:
CERNBox is the CERN cloud storage hub for more than 25,000 users at CERN. It allows synchronising and sharing files on all major desktop and mobile platforms (Linux, Windows, MacOSX, Android, iOS) providing universal, ubiquitous, online- and offline access to any data stored in the CERN EOS infrastructure. CERNBox also provides integration with other CERN services for big science: visualisation tools, interactive data analysis and real-time collaborative editing. Over the last two years, CERNBox has evolved from a pure cloud sync and share platform into a collaborative service, to support new applications such as DrawIO for diagrams and organigrams sketching, OnlyOffice and Collabora Online for documents editing, and DXHTML Gantt for project management, as alternatives to traditional desktop applications. Moving to open source applications has the advantage to reduce licensing costs and enables easier integration within the CERN infrastructure. This move from commercial software to open source solutions is part of the MALT project, led by the IT department at CERN to reduce the dependencies on commercial solutions. As part of the MALT project, CERNBox is the chosen solution to replace Home directories of the Windows DFS file system. Access to storage from Windows managed devices for end-users is largely covered by synchronization clients. However, online access using standard CIFS/SMB protocol is required for shared use-cases, such as central login services (Terminal Services) and visitor desktop computers. We present recent work to introduce a set of Samba gateways running in High Availability cluster mode to enable direct access to the CERNBox backend storage (EOS).

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.

Purpose The purpose of this paper is to provide a flexible and extensible model for the classification of suppliers, within the purchasing guidelines and market trends of an Italian small company, leader in the production of street lamps. The model is applied to identify critical supply chains with the final objective of lead-time reduction. Design/methodology/approach The model is obtained by the application of the purchasing portfolio analysis through the construction of Kraljic matrix. Profit impact and supply risk criteria are selected according to the main company requirements, and then prioritized by the analytical hierarchy process (AHP). Finally, supply chain lead-times are analyzed with Gantt diagrams. Findings The application of the model allows the determination of company criticalities in terms of high lead-times and of the involved suppliers. The analysis of critical suppliers positioning in the Kraljic matrix allows the definition of some possible strategies to implement for lead-time reduction. Research limitations/implications Purchasing portfolio analysis and Kraljic matrix are practical instruments to quickly frame company purchasing situation, but their application is not simple due to the numerous and different factors involved, especially in small and medium enterprises (SMEs), where resource are scarce and several constraints limit operations. The objective of the research is the development of a practical tool for strategic purchasing, simple and robust to be implemented in SMEs, with limited resources and access to quantitative supplier data. Originality/value Evaluation criteria definition is one of the most difficult phases, such as their univocal and quantitative comparison. The problem of selecting and prioritizing both quantitative and qualitative criteria for suppliers classification is overcome with the combined application of Kraljic matrix and AHP. The newly integration of the two methodologies allows the realization of a reliable and robust model for suppliers classification, which can be easily adapted to company business strategy changes.

Business process modeling attracts great importance in enterprises due to the need for a graphically simplified and less verbal way to manage their operations. Nevertheless, the existence of various process modeling standards across the different departments of the same enterprise, such as Business Process Modeling Notation (BPMN) diagrams, classic flowcharts, Gantt charts and Petri nets, urges their notation alignment. After the business process model nota-tion alignment, complex constraints and relationships among the enterprise's department processes can be automated and simplified. In the light of the digital transformation of today's enterprises, the main objective of this paper is the proposal of a straightforward and simplified business educational equivalence table so that a direct conversion among BPMN diagrams, flowcharts, Gantt Charts and Petri Nets can be locally fulfilled by non-specialized personnel in each enterprise's department. The methodology of this paper can be generalized in every enterprise where the aforementioned process modeling standards across its different departments coexist.

Na linha de produção de uma indústria automobilística podem ocorrer diversos problemas que quando não identificados e tratados corretamente são capazes de afetar a satisfação do cliente e a imagem da empresa. Um dos grandes desafios diários é evitar que esses problemas levem ao surgimento de defeitos nos veículos, impedindo assim que cheguem aos clientes produtos com anomalias. Desse modo, o presente artigo tem como objetivo demonstrar como o método Kaizen e o PDCA contribuem com o gerenciamento da linha de produção com objetivo de 0 defeito e aplicação de contramedidas eficientes. Para isso, foi realizada uma pesquisa-ação utilizando a metodologia Kaizen para acompanhar a linha de produção. Após a identificação de uma oportunidade de melhoria no processo de fixação da mostrina foram empregadas as ferramentas da qualidade brainstorming, gráfico de Pareto, diagrama de causa e efeito, 5W2H (plano de ação), 5G’s e o diagrama de Gantt, atingindo a aplicação completa do PDCA.

Full textAbstract:
The article analyses the candied fruit market in Ukraine and describes the main technological operations pertainingto processing of non-traditional candied products – celery and parsnip roots. Darkening of the roots surface caused bythe enzyme oxidation is one of the problems arising when processing white roots, which leads to worse marketable conditionof the product. To prevent darkening, the developed technology provides for soaking raw material in 1% citric acid solutionimmediately after peeling. To improve the diffusion and osmotic processes and to soften roots before boiling in sugar syrup,the steam blanching has been applied. The constructed Gantt diagram proves that the developed technology can shorten thecandied fruit cooking period. The biochemical indicators of the obtained new products have been studied. It was establishedthat the candied fruit possess the appropriate physical and chemical indicators and original organoleptic properties resulting ina demand by consumers. The results of the taste evaluation of the experimental specimen confirmed a high quality of the products.

Full textAbstract:
<p>En el presente documento se aborda la problemática de lo que significa el establecer los objetivos parciales de un proyecto, cuando se minimiza su importancia o se carece de fundamento. En ocasiones se recurre al diagrama de Gantt como solución, pero como se verá más adelante, ésta no es la mejor opción. Un mal planteamiento de estos objetivos, puede alterar la asignación de tareas y por ello, el no arribar a los resultados esperados, en un descontrol manifiesto en recursos materiales y humanos.<br />La propuesta consiste en recurrir a la técnica de Project Evaluation and Review Technique, que permite determinar en tiempos estimados las actividades a desarrollar. De ahí, al agruparlas se conforman lo que son los objetivos parciales. Esta es una propuesta que evita la imposición de objetivos, ya que al aglutinar actividades de manera racional, estos objetivos se establecen como una consecuencia y no como una condición.</p>

El objetivo principal fue mejorar el Sistema HACCP existente para asegurar la inocuidad del producto “anchoveta en salazón” de una empresa pesquera. La investigación de tipo aplicada fue de diseño preexperimental. La muestra estuvo conformada por los datos de concentración de histamina, como factor de la inocuidad del producto, de 5 meses del año 2018 y 4 del año 2019. Para la mejora del sistema HACCP se utilizó un registro de verificación, plan de mejora, diagrama de Gantt y Formatos HACCP; para la variable de inocuidad se utilizó un registro de análisis físico sensorial de la materia prima y registro de inspección del producto terminado. Teniendo como resultados que solo 4 aspectos alcanzaron su puntaje mínimo de aprobación; el contenido de histamina inicial en materia prima aumentó un 24.6% y en el producto terminado un 33.19%, y una disminución en la calidad de la materia prima un 20.54%; el diseño e implementación del Plan consistió en los 12 pasos del Sistema HACCP donde se encontraron 1 PCC más (salado), a través de una matriz de evaluación de peligros y se implementaron diferentes formatos; el peligro químico disminuyó en un 20.05% (materia prima) y 25.73% (producto terminado) y en cuanto al peligro biológico, la calidad de la materia prima aumentó en un 14.83%. Concluyendo que la implementación de la mejora del Sistema HACCP asegura la inocuidad del producto de la empresa pesquera de manera significativa.
