Reactive project scheduling is an important branch of under uncertainty. This paper proposes a resource-constrained multi-project reactive problem (RCMPRSP) with new arrival to minimize the adjustment cost baseline schedule while achieving deterministic goal. Although RCMPRSP aims cost, it adds constraint ensure that one schedules shortest possible make-span after arrival. Therefore, and can bo...

This paper reviews compact continuous-time formulations for the multi-mode resource-constrained project scheduling problem. Specifically, we first point out a serious flaw in an existing start-end-event-based formulation owing to inconsistent mode choices. We propose two options formulate missing constraints and consider equivalent reformulation with sparser constraint matrix. Second, aggregate...

Projects became part of the daily business in many functional areas, across industries and services. Despite variety project execution implementation different domains it is visible that projects are sharing fundamental similiarities. Based on experiment success a exuecution depends - next to maintained data quality follow-up ability schedule activities an optimized way. Scheduling even more co...

In this paper, we present part of a study on stochastic, dynamic project scheduling in an R&D Department of a leading home appliances company in Turkey. The problem under consideration is the preemptive resource constrained multi-project scheduling problem with generalized precedence relations in a stochastic and dynamic environment. The model consists of three phases. Phase I of the model prov...

extensive research has been devoted to resource constrained project scheduling problem. however, little attention has been paid to problems where a certain time penalty must be incurred if activity preemption is allowed. in this paper, we consider the project scheduling problem of minimizing the total cost subject to resource constraints, earliness-tardiness penalties and preemption penalties, ...

In this paper, a novel mathematical model for a preemption multi-mode multi-objective resource-constrained project scheduling problem with distinct due dates and positive and negative cash flows is presented. Although optimization of bi-objective problems with due dates is an essential feature of real projects, little effort has been made in studying the P-MMRCPSP while due dates are included i...

In practice, organizations work in general on more than one project which share some or all the available resources. In this work hybrid heuristics that combine Random Sampling heuristics and Backward-Forward methods are developed for the Resource-Constrained Multi-Project Scheduling Problem (RCMPSP). This heuristic approach has been successfully applied to resource-constrained single project s...
