Abstract

Data Envelopment Analysis (DEA) is a procedure to measure the relative efficiency of decision‐making units in situations where there are multiple inputs and outputs with no obvious objective way of aggregating these multiple inputs and outputs into a meaningful index of productive efficiency. A systematic application of DEA in Saudi Arabia is presented – carried out at a small college to assess the relative efficiency of teaching staff. The DEA technique and the data are described, and the results of the analysis are discussed.

Abstract

In this article, a PC‐based spreadsheet support system (SSS) for controlling inventory and service level for the newsboy problem is developed utilising Lotus 1‐2‐3 spreadsheet capabilities. The technical aspects of the SSS are presented and discussed within the context of a numerical example. The developed SSS permits the decision maker to simulate and analyse the impact of parameter changes on the inventory system using a familiar PC spreadsheet package.

Abstract

Details a data envelopment analysis (DEA) study of bank branches, where the bank branches are considered as the decision‐making units (DMUs). The Charnes, Cooper and Rhodes (CCR) ratio is used to evaluate the relative efficiency of each branch. The relative efficiency is computed utilizing specific input and output factors. The study has been applied to a set of branches of one of the largest commercial banks in Saudi Arabia in an attempt to evaluate the relative efficiency of these branches in order to improve the quality of services and utilize the available resources more efficiently.

Abstract

Spreadsheet software is now widely used as a decision‐making tool, owing to the simplicity and ease with which generalists can analyse and obtain fast and precise information. Through spreadsheet programs, a non‐specialist can conduct an exhaustive “what if” search in order to make decisions regarding “what if” questions. Now, with the availability of a random number function in most spreadsheet programs, simulation models can be carried out within the spreadsheet. How the waiting‐line problem can be simulated using a spreadsheet package is demonstrated. The simulation process serves as a decision‐support system to assist decision makers to determine the appropriate service level based on number of servers. Arrival of customers to obtain service is stochastic in nature and therefore can be assigned a probability distribution using historical data. Through the random‐number function, which is available in most spreadsheet programs, random numbers can be generated and used along with the assigned probability distribution to assist in making the service‐level decision.

Abstract

At present, manufacturing firms in the Kingdom of Saudi Arabia (KSA) are considering the adoption of quality control (QC) techniques. Conducts a survey to investigate the awareness of quality and to shed some light on the extent of the practice and content of the QC process in manufacturing firms in KSA.
