The Project Scheduling Problem with Non-Deterministic Activities Duration: A Literature Review

Purpose: The goal of this article is to provide an extensive literature review of the models and solution procedures proposed by many researchers interested on the Project Scheduling Problem with nondeterministic activities duration. Design/methodology/approach: This paper presents an exhaustive literature review, identifying the existing models where the activities duration were taken as uncertain or random parameters. In order to get published articles since 1996, was employed the Scopus database. The articles were selected on the basis of reviews of abstracts, methodologies, and conclusions. The results were classified according to following characteristics: year of publication, mathematical representation of the activities duration, solution techniques applied, and type of problem solved. Findings: Genetic Algorithms (GA) was pointed out as the main solution technique employed by researchers, and the Resource-Constrained Project Scheduling Problem (RCPSP) as the most studied type of problem. On the other hand, the application of new solution techniques, and the possibility of incorporating traditional methods into new PSP variants was presented as research trends. Originality/value: This literature review contents not only a descriptive analysis of the published articles but also a statistical information section in order to examine the state of the research activity carried out in relation to the Project Scheduling Problem with non-deterministic activities duration.Peer Reviewe

Course Scheduling Optiimization with Zero-One Linear Goal Programming Method

Abstrak Penjadwalan perkuliahan di perguruan tinggi membutuhkan model matematik yang dapat memaksimumkan kepuasan dosen dan mahasiswa. Penelitian ini menggunakan Zero-One Linear Goal Programming (0-1 LGP) untuk mengoptimasi penjadwalan perkuliahan di sebuah perguruan tinggi di Jakarta. Pendapat 50 orang responden yang terdiri dari mahasiswa dan dosen, diolah dengan metode AHP, untuk mendapatkan prioritas kriteria dalam penyusunan penjadwalan perkuliahan. Penelitian ini membuktikan metode 0-1 LGP secara efektif dapat digunakan untuk meningkatkan kepuasan dosen dan mahasiswa terhadap jadwal perkuliahan. Kata kunci: penjadwalan mata kuliah, kriteria, metode AHP, prioritas, metode Zero-One Linear Goal Programming, tingkat kepuasan  Abstract University course scheduling requires mathematical model to maximize the student and lecturer satisfaction. This research uses  Zero-One Linear Goal Programming (0-1 LGP) to optimize the course scheduling in a university in Jakarta. The data colletted from fifty students and lecturers was processed by using AHP to get the priority kriteria of course scheduling. This reseach shows that 01 LGP can be used for effective course scheduling which to improve the student and lecturer satiscation level. Keywords: courses scheduling, criteria, AHP, Priority, Zero One Linear Goal Programming, satisfation leve
