Abstract
  The Flexible Job shop Scheduling Problem (FJSP), as a Production Scheduling Problem (PSP), is generally an extension of the Job shop Scheduling Problem (JSP). In this paper, the FJSP with reverse flow consisting of two flows of jobs (direct and reverse) at each stage is studied; the first flow initiates ...  Read More

Abstract
  The continuous growth of the population causes an increased demand for our healthcare services. Insufficient hospitals face challenges to serve the patient within a preferable duration. Long lines in front of counters increase the processing time of a patient. From the entry to the completion, plenty ...  Read More

Development of a doctor scheduling system: a constraint satisfaction and penalty minimisation scheduling model

T. Chawasemerwa; I. W. Taifa; D. Hartmann

Volume 7, Issue 4 , December 2018, , Pages 396-422

https://doi.org/10.22105/riej.2018.160257.1068

Abstract
  Doctor scheduling is a complex, costly and time-consuming exercise. This study develops a constraint satisfaction and penalty minimisation scheduling model for meeting ‘hard constraints’ and minimises the cost of violating ‘soft constraints’, i.e. the user inputs, the total number ...  Read More

Volume 5, 1(4) , November 2016, , Pages 1-15

https://doi.org/10.22105/riej.2017.49167

Abstract
  This paper considers the problem of university course timetabling. In this problem, there are a set of courses, lecturers and classrooms. The objective is to assign schedule courses so as to maximize the total preference of lecturer-course, lecturer-day and course-day. The paper first formulates the ...  Read More
