We introduce a multimode resource-constrained project scheduling problem with finish-to-start precedence relations among project activities, considering renewable and nonrenewable resource costs. We assume that renewable resources are rented and are not available in all periods of time of the project. In other words, there is a mandated ready date as well as a due date for each renewable resour...

The discrete time –cost trade-off problem (DTCTP) is one of the main aspects of project scheduling. In DTCTP , we treat cost as a non-renewable resource and the availability of renewable resource per period has been neglected. It was recently suggested that the quality of project should also be taken into consideration. Therefore, when renewable resources and quality are considered, the traditi...

In this paper, we present a unified framework for production planning and scheduling in make-to-order manufacturing. Both planning and scheduling problems are captured as resource-constrained project scheduling problems. The actual models and solution techniques are different at the two levels. Hence, we also suggest an aggregation method that provides the connection between planning and schedu...

Resource Constrained Project Scheduling Problem is a very important problem in project management, manufacturing and resource optimization. We focus on a variant of RCPSP with time lags and variable activity durations. The solving approach is based on Precedence Constraint Posting that adds new precedence constraints to the original project graph so that all resource conflicts are solved and a ...

We define a language RS , a subclass of the scheduling language RSV (resource constrained project scheduling with variant processes). RS involves the determination of the starting times for ground activities of a project satisfying precedence and resource constraints, in order to minimize the total project duration. In RS ground activities and two structural symbols (operators) ‘seq’ and ‘pll’ ...

In this paper, we consider the Resource Constrained Project Scheduling Problem (RCPSP). New feasibility tests for the energetic reasoning are introduced based on new integer programming (IP) formulations. Experimental results are presented based on PSPLIB instances.

The resource-constrained project scheduling problem (RCPSP) consists of activities that must be scheduled subject to precedence and resource constraints such that the makespan is minimized. It has become a well-known standard problem in the context of project scheduling which has attracted numerous researchers who developed both exact and heuristic scheduling procedures. However, it is a rather...

Resource Constrained Project Scheduling Problems (RCPSP), especially their stochastic variants, and the methods operating on them represent a general project scheduling optimization framework. This paper presents the survey of methods and models that are put into the historical context and are categorized according to their working principles. It aims to supplement and update existing RCPSP sur...
