“…Data-driven categories were established during the analysis, following the six phases for a thematic analysis that guided the works of Hossain et al (2020) and Marikyan et al (2019). The purpose is to identify, analyze, and report patterns in the form of themes (Afshar-Nadjafi, 2020;Snyder, 2019). In phase 1, the 74 documents were read to increase the familiarity with the topic of interest, as well as the knowledge regarding some patterns of analysis.…”

“…A semi-systematic literature review was selected as the research method for the current study. This research approach is designed to provide an overview of a topic such as the consumer decision journey that has been studied and conceptualized differently by diverse groups of researchers within various disciplines and which, as a consequence, can hinder a full systematic review process (Afshar-Nadjafi, 2020). This type of review intends to identify and understand all the relevant research traditions that have implications for the researched topic, with the aim of synthesizing them through the use of meta-narratives, rather than measuring effect sizes (Wong et al, 2013).…”

“…Particularly, most of the studies focused on MS-RCPSP merely assume that all tasks to be scheduled belong to the same project. In this review, we focus on a multi-project setting, the reader interested in the mono-project case is referred to the papers by [5], [6].…”

This paper addresses an industrial case of the twoagent scheduling problem with a global objective function. Each agent manages one or several projects and competes with another agent for the use of common multi-skilled employees. There is a pool of employees, each of which can perform a set of skills with heterogeneous performance levels. The objectives of the two agents are both to minimize the total weighted tardiness of its tasks. Furthermore, We assume that some constraints (soft constraints) can be violated when there is no feasible schedule for the problem. Thus, the global objective function minimizes the constraint violations by reducing the undesirable deviations in the soft constraints from their respective goals. The overall objective is to find a schedule that minimizes both agents objective functions (local objectives) and the global objective function. We provide a mixed-integer goal programming (MIGP) formulation for the problem. In addition, we present a hybrid algorithm combining an exact procedure, a greedy heuristic, and a genetic algorithm to find an approximate Pareto solution set. We compare the performance of the hybrid algorithm against the corresponding MIGP formulation with simulated instances derived from realworld instances.

“…The surveys of [16], [1] and Abdalkareem et al [17] cover scheduling of all types of personnel of a hospital (or health care unit), propose alternative classifications, identify research gaps. On the other hand, the literature review of Afshar-Nadjafi [18] accounts for the different sets of skills and levels of proficiency. Finally, Gür and Eren [19] detail the applications of GP to scheduling and planning in service systems.…”

This paper proposes a literature review and a mathematical goal program for the design of timetables for radiologists. The goal program converts the tedious monthly tasks of the head of the radiology department of a leading hospital to a simple goal optimization problem that abides to the regulations of the Ministry of Health and avoids conflicting issues that may arise among coworkers. The optimization problem which is designed for the tactical level can also be used at the strategic level (i.e., account for a long time horizon) to plan for longer term constraints such vacations, medical and study leaves, recruitment, retirement, etc. Despite its large size, the problem is herein solved using an off-the-shelf solver (CPLEX). Empirical tests on the design of timetables for the case study prove the efficiency of the obtained schedule and highlights the time gain and utility of the developed model. They reflect the practical aspects of timetabling and radiologists' availability. Specifically, not only does the model and its solution reduce the effort of the Department head in this design stage, but it also promotes social peace among the technicians and a sense of fairness / unbiasedness. In addition, the designed model can be used at the operational level as a rescheduling tool by those technicians wishing to trade their shifts, and as a sensitivity analysis tool by managers wishing to study the effect of some phenomena such as absenteeism, increasing or decreasing the workforce, and extending work hours on the welfare of patients.
