Based on the situation of the construction and software industry, this paper presents a multi-skilled human resource scheduling model which considers the skill and the salary of the workforce at different levels. It introduces a novel cuckoo search (CS)-based approach to optimize the objective function which combines the minimization of the makespan and the project cost. The proposed approach t...

Multi-skilled resources have brought more flexibility to resource scheduling and been a key factor in the research of resource-constrained project problems. However, existing studies are mainly limited deterministic problems neglect some uncertainties such as breakdowns, while availability may change over time due unexpected risks COVID-19 pandemic. Therefore, this paper focuses on multi-skille...

We study an assignment type resource-constrained project scheduling problem with resources being multi-skilled personnel to minimize the total staffing costs. We develop a hybrid Benders decomposition (HBD) algorithm that combines the complimentary strengths of both mixed-integer linear programming (MILP) and constraint programming (CP) to solve this NP-hard optimization problem. An effective c...

During project execution, especially in a multi-project environment project activities are subject to risks that may cause delays or interruptions in the baseline schedules. This paper considers the resource constrained multi-project scheduling problem with generalized activity precedence relations requiring multi-skilled resources in a stochastic and dynamic environment present in the R&D depa...

Proper and realistic scheduling is an important factor of success for every project. In reality, project scheduling often involves several objectives that must be realized simultaneously, and faces numerous uncertainties that may undermine the integrity of the devised schedule. Thus, the manner of dealing with such uncertainties is of particular importance for effective planning. A realistic sc...

This paper studies and analyses the multi-skilled resource-constrained project scheduling problem (MSRCPSP). We present a new classification scheme based on an existing for problems. allows researchers to classify all problems its extensions. Furthermore, we propose data generation procedure MSRCPSP introduce multiple artificial datasets varying research purposes. The are generated resource par...

A recurring problem in project management involves the allocation of scarce resources to the individual jobs comprising the project. In many situations such as audit-staff scheduling, timetabling, and course scheduling, the resources correspond to individuals (skilled labour). This naturally leads to an assignment-type project scheduling problem, i.e. a project has to be performed by assigning ...

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...
