In this paper we analyze a queueing network consisting of parallel queues and arriving customers that have to be assigned to one of the queues. The assignment rule may not depend on the numbers of customers in the queues. Our goal is to find a policy that is optimal with respect to the long-run average cost. We will consider two cases: holding costs and waiting times. A recently developed algorithm for Markov decision chains with partial state information is applied. It turns out that the periodic policies found by this algorithm are close, if not equal, to the optimal ones.

In this paper, an integrated simulation optimization model for the assignment problems is developed. An effective algorithm is developed to evaluate and analyze the back-end stored simulation results. This paper proposes simulation tool SIMASI (Simulation of assignment models) to simulate assignment models. SIMASI is a tool which simulates and computes the results of different assignment models. This tool is programmed in DOT.NET and is based on analytical approach to guide optimization strategy. Objective of this paper is to provide a user friendly simulation tool which gives optimized assignment model results. Simulation is carried out by providing the required values of matrix for resource and destination requirements and result is stored in the database for further comparison and study. Result is obtained in terms of the performance measurements of classical models of assignment system. This simulation tool is interfaced with an optimization procedure based on classical models of assignment system. The simulation results are obtained and analyzed rigorously with the help of numerical examples.

This article reports on a proposed evaluation plan that has been developed to assess the work done by the State Information Technology Agency (SITA). The SITA programme was implemented in response to the South African government’s call to improve the lives of the populations in some rural areas through technology. The programme was meant to address slow development in  rural  areas  that  lack  technological  innovations  and  advances.  In  the proposed evaluation plan a review is made of secondary data, deciding how strategic priorities are to be determined, as well as analysis of the rural context environment. The researcher gives an account of how the evaluation strategies are to be piloted and rolled out thereafter. Lessons learnt are recorded and reported upon. A proposed evaluation plan will be developed, based on the lessons learnt in line with the objectives of the project.
