Abstract

The supervision of a complex system involves the study and analysis of its operation as well as a continuous search for its improvement and optimization. Simulation in general, and discrete simulation in particular, is an appropriate tool to support different management policies and strategies. In order to carry out a simulation project, special importance must be given to the simulation process, which has led us in this paper to ask the question: is there a standard life cycle of a simulation project? or a repository of the steps to follow? In this paper, we have used the most frequently cited simulation steps in the literature to develop a simulation project life cycle called SPLC (Simulation Project Life Cycle) grouping together the main steps. Then, we were interested in the analysis of the level of use of each of the steps retained by the simulation processes described in the simulation studies considered in the literature review. Secondly, we tried to put the elaborated SPLC cycle into action through a simulation case study, this is the voluntary departure operation launched in Morocco in 2005. Thus, we carried out a simulation allowing to analyze the success rate of this operation, and also its impact on the state of the Moroccan pension fund, and this for the period going from 2005 to 2025. The study was carried out on a set of generated data randomly according to statistical distributions.

Highlights

  • Since simulation is a decision support technique, it plays an important role in modeling systems when the direct or analytical solution is too complex [1–4] or when the problem is random

  • We present the context of a simulation study, focusing on the relevance of the operation voluntary departure from the Moroccan civil service launched in 2005, as well as the detailed development of this simulation according to the proposed SPLC

  • The methodology followed during the development of a simulation project is based on steps which are not always mentioned in the simulation processes described in the various studies on the subject

Summary

Introduction

Since simulation is a decision support technique, it plays an important role in modeling systems when the direct or analytical solution is too complex [1–4] or when the problem is random. Morocco launched a voluntary early retirement program in 2005 for public officials [8] in return for an incentive allowance and a pension calculated on the basis of years of service This voluntary departure operation was the subject, in this paper, of a simulation case study which will make it possible to analyze, over time, the relevance of this decision of the government at the beginning of the millennium, the rate of its success, as well as its impact on the state of the Moroccan pension fund already in crisis. We present the context of a simulation study, focusing on the relevance of the operation voluntary departure from the Moroccan civil service launched in 2005, as well as the detailed development of this simulation according to the proposed SPLC. The sixth and last section retraces the main lines of this paper, both in terms of existing simulation processes and avenues that we intend to explore in our future work, and in terms of the simulation study carried out and potential axes to study
