Scheduling Tool

This paper introduces a set of integrated software tools that improve a shipyard’s ability to conduct effective capacity planning and analyses as well improve their spatial scheduling throughout all their facilities. The Long-Range Capacity Planning Tool replaces a manually intensive planning process through a user-friendly interface. The Spatial Scheduling Tool is a vastly improved version of previously developed software (Finke et al., 2007; 2008) to determine which areas of the shipyard are in use throughout the build plan. Finally, a Shop-Level Capacity Planning Tool is introduced that provides planners a view of work order schedules and their impact on work center capacity. These tools can be used to generate and save different build plan scenarios to perform what-if analyses and to perform more accurate capacity analyses to explore how adding a new hull to the build plan will affect current production plans. These tools interface with a Central Data System, which extracts information from legacy data systems, and acts as the central repository for all capacity planning data, ensuring that the tools have identical and up to date information. The tools also provide reporting/export functions that enable efficient integration back to the shipyard’s legacy execution system.

Planning Approach

PurposeThis paper aims to present a unified approach for effective capacity management, with the flexibility to position the organization across differing market‐orientations, anywhere from produce‐to‐stock to purchase‐and‐produce‐to‐order.Design/methodology/approachThe unified planning system combines capacity management with the external market through the customer order decoupling point (CODP). The approach starts by determining the CODP, using commonality and effect‐cause‐effect analysis. The resulting CODP information is then used to determine the optimal master production schedule (medium‐term), as well as the detailed schedule (short‐term) at the bottleneck resource, using mathematical programming; to support decisions across different planning horizons in an integrated fashion.FindingsThis unified approach was applied to an electronics manufacturing company in the Netherlands. The unified capacity planning system not only reduces the number of capacity problems to be solved by production planners, but also more importantly enhances the organization's capabilities to respond faster and more focused to market changes.Research limitations/implicationsFurther studies may test the robustness of this planning approach with additional empirical evidence.Practical implicationsThe structured unified approach provides a comprehensive solution to a complex capacity management problem, in competitive environments where organizations have to be able to respond to dynamically changing market conditions, given the process choices within which they are operating.Originality/valueProvides a unified approach for effective capacity management.

In this paper we describe the development and implementation of a tool that allows shipyard planners and construction managers to efficiently and effectively plan work area space within large manufacturing facilities. Currently, there are no software planning tools available to explicitly plan and schedule critical manufacturing space. The activity-based spatial scheduling tool described in this paper can be used by planners and construction management teams to easily reserve space within shipyard facilities for the construction and outfitting of large units. The Activity-Based Spatial Scheduling Tool gives users the ability to rapidly generate and compare multiple space allocation plans, with the ultimate goal of maintaining the critical ship construction schedule.

Municipal Level

The late formal tradition of strategic environmental assessment (SEA) European Directive into the Italian planning system has so far induced a variety of behaviour of administrative bodies and planning agencies involved. In Italy and Sardinia, a new approach to landscape planning is characterizing spatial planning practice from the regional to the municipal level. Currently municipalities are adjusting their master plan to the prescriptions of the regional landscape planning instrument (in Italian, Piano Paesaggistico Regionale, PPR), according to processes that have to be integrated with a proper SEA development. With respect to this background, the aim of this paper is to assess the level of SEA implementation on the master plans of Sardinia six years after the approval of the PPR. The first results show that many municipalities are not provided with a master plan (in Italian, Piano Urbanistico Comunale, PUC) and they have in force just an old planning tool. Moreover, just some municipalities have adapted the PUC to the PPR carrying out a SEA process.

Transit Accessibility

Accessibility analysis can have important implications for understanding social equity in transit planning. The emergence and the increasingly broad acceptance of the general transit feed specification (GTFS) format for transit route, stop, and schedule data have revolutionized transit accessibility research by providing researchers with a convenient, publicly available source of data interoperable with common geographic information system (GIS) software. Existing approaches to GTFS-based transit analysis, however, focus on currently operating transit systems. With major transit expansions across the nation and around the world increasing in number and ambition, understanding the accessibility impacts of proposed projects in their early planning stages is crucial to achieving the greatest possible social benefit from these massive public investments. This paper describes the development of a hypothetical transit network based on current GTFS data and proposed 2040 transit improvements for the Twin Cities region of Minneapolis–Saint Paul, Minnesota, as well as its use as a sketch planning tool in exploring the proposed system’s impacts on access to job vacancies from historically disadvantaged areas. This research demonstrates the importance of accessibility analysis in planning a transit system that increases opportunity for marginalized workers and concludes by calling for broader, easier access to accessibility analysis for practitioners and community groups to refine the early stages of the transit planning process and democratize an increasingly crucial transit planning tool.

Ontology Merging

This article describes the method of integrating information systems of an aircraft factory with the production capacity planning system based on the ontology merging. The ontological representation is formed for each relational database (RDB) of integrated information systems. The ontological representation is formed in the process of analyzing the structure of the relational database of the information system (IS). Based on the ontological representations merging the integrating data model is formed. The integrating data model is a mechanism for semantic integration of data sources.

Conscious Control

The attempts to build post-capitalist societies in the twentieth century all used variations of the material-balances economic planning procedures developed first in the USSR. Most advocates of transcending capitalism came to accept the idea that the desired new society could operate only with some variation of such an economic planning tool. One part of the current thorough reconsideration of how to build a human-centered post-capitalist society is reconsidering how it should carry out, in a way consistent with its goals, the social economic planning that all systems of production require. This brief work first addresses a number of misconceptions and myths connected with the identification of planning for socialism with the material-balances planning system. After that, and connected to real-world experiments now going on in a few countries in the world, the work considers if the required social economic planning could occur through conscious control of markets, for countries attempting to build a socialism that uses markets for both the necessary articulation of all the steps in its many production chains and for the distribution of consumer goods.

This paper highlights the opportunities and challenges of applying Discrete Event Simulation (DES) to support capacity planning of a network of outpatient facilities. Despite an abundance of studies using simulation techniques to examine the operation and performance of outpatient clinics, the problem of capacity allocation and planning of medical services within a network of outpatient healthcare facilities appears to be underexplored. Here, a case study of a health insurance provider that operates a network of six outpatient medical facilities in the US is used to illustrate and explore the synthesizing and adaptive, yet parsimonious nature of using DES methodology for network design and capacity planning. Results of this case study demonstrate that significant performance improvements for the network operator can be achieved with applying DES method to support the network facility capacity planning process.

Electricity Access

Access to power is tied to a country's development. It facilitates improved social welfare, education, health and income generating opportunities. Uganda's economy is stifled by its low electrification rates - 16% nationally. This study builds a working theory on the internal setup of Uganda's power sector utilizing this theory to surface influential behavior modes as they pertain to power generation and supply and how these ultimately affect electricity access. Based on this working theory a System Dynamics simulation model is built. The model simulations show how Uganda's power sector is expected to evolve over 80 years in terms of power supply and demand given existing market structure and prevailing conditions. The study finds major problems in the nature of power accessed specifically an insufficient and unreliable power supply. The root cause is found in the nature of the existing capacity planning process in terms of how future capacity requirements are determined and the agreements made with generators as to how and when they fulfill their investment obligations.

Urban regeneration has been at the forefront of urban planning and development in European cities for many decades and is strongly connected to property-led development, with the involvement of various stakeholders. In Greece, urban regeneration, as a public policy response to large-scale abandonment and dereliction of urban land, has not been successful so far. The Greek planning system and its provisions for renewal of degraded urban areas have for long been regarded as an obstacle to the implementation of urban regeneration projects. The reform of the planning system in the 2010s introduced some critical changes, with an emphasis on larger-scale development, but with no particular focus on urban regeneration. Using two case studies of regeneration projects in the city of Thessaloniki, this paper attempts to provide an insight into the role of the various stakeholders in such projects. It is argued that in these projects, each stakeholder, irrespective of its character, acts as distinct interest group which develops only binary relations with other stakeholders. Thus, the regeneration project becomes a platform upon which each stakeholder aims to secure its power, instead of a coordinated multi-stakeholder process with a framework for sharing the costs and benefits of its implementation.

ABSTRACT Objective: Health system preparedness for coronavirus disease (COVID-19) includes projecting the number and timing of cases requiring various types of treatment. Several tools were developed to assist in this planning process. This review highlights models that project both caseload and hospital capacity requirements over time. Methods: We systematically reviewed the medical and engineering literature according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We completed searches using PubMed, EMBASE, ISI Web of Science, Google Scholar, and the Google search engine. Results: The search strategy identified 690 articles. For a detailed review, we selected 6 models that met our predefined criteria. Half of the models did not include age-stratified parameters, and only 1 included the option to represent a second wave. Hospital patient flow was simplified in all models; however, some considered more complex patient pathways. One model included fatality ratios with length of stay (LOS) adjustments for survivors versus those who die, and accommodated different LOS for critical care patients with or without a ventilator. Conclusion: The results of our study provide information to physicians, hospital administrators, emergency response personnel, and governmental agencies on available models for preparing scenario-based plans for responding to the COVID-19 or similar type of outbreak.
