In decentralized construction projects, costs are mostly related to investment, material, holding, logistics, and other minor costs for implementation. For this reason, simultaneous planning of these items and appropriate scheduling of activities can significantly reduce the total costs of the project undertaken. This paper investigates the decentralized multiple construction projects schedulin...

In traditional approach, planning and scheduling are two separate and successive operations. The process planning phase is mostly about the physical aspect of planning, where a product range, production quantities, machines, tools, material and accessories are selected. The emphasis in the second, scheduling phase, is on the time aspect. The plan is the basis to determine the sequence of operat...

The development of a public test bed for manufacturing planning and scheduling brings a lot of design issues, along several dimensions: the content of the test bed, the testing protocol, the format of the data, and the management of the results obtained. The objective of the present paper is to discuss these issues and explain the rationale behind the choices that have been made in MaScLib, a l...

The advances of production technologies reflect a worldwide trend for sustainability and rational use of resources. As a consequence, some movements for industry reorganization can be observed in geographically dispersed systems with new productive systems (PSs) configurations. These PSs work with small and medium size production lots, product families with increasing variety, and hard delivery...

This paper describes the application of Artificial Intdligenre planning techniques to the problem of antenna track plan generation for a NASA Deep Space CommunicationJ Station. The described system enables an antenna communicatiwnJ station to automatically re,pond to a set of tracking goals by correctly configuring the appropriate hardware and software to provide the requested communication ser...

Organizations need to evaluate project proposals and select the ones that are the most effective in reaching the strategic goals by considering sustainability issue. In order to enhance the effectiveness and the efficiency of project oriented organizations, in this paper a new multi-objective decision making (MODM) approach of sustainable project portfolio selection is proposed which applies in...

This paper deals with a special case of Project Scheduling problem: there is a project to schedule, which is made up of activities linked by precedence relations. Each activity requires specific skills to be done. Moreover, resources are staff members who master fixed skill(s). Thus, each resource requirement of an activity corresponds to the number of persons doing the corresponding skill that...

We review the 2016 International Competition on Knowledge Engineering for Planning and Scheduling (ICKEPS), the fifth in a series of competitions started in 2005. ICKEPS series focuses on promoting the importance of knowledge engineering methods and tools for automated Planning and Scheduling systems.

The complexity of planning and scheduling is determined by the degree to which activities contend for resources. Accordingly this requires any application to have the ability to reason about the nature of the resource and its availability. This paper presents a generic enterprise resource ontology. The ontology described in this paper is one of many that is being created by the TOVE project in ...

This article analyzes the issues related to designing a regular competitive evaluation for automated scheduling systems. We provide some specific guidelines for designing the competition, and we set out to understand the benefits as well as the drawbacks of its implementation. Both issues are discussed over the backdrop of current relevant competitions in Computer Science.
