This paper demonstrates a new approach in solving problems with capacity issues within a cement factory in Libya using the Witness simulation package that enables the development of discrete and continuous simulation model to simulate these processes. The model aims to support the implementation of management systems in Supply Chain Management and the introduction of Just-In-Time systems. In order to carry out the above, research has been carried out into processes of SCM and J.I.T. The developed Simulation model is based on Libyan Cement industry, exploring supply chain management (SCM) and Just IN Time (JIT) system from start to end of the processes. Therefore, the aim and objective of investigating supply chain management and applying JIT to the cement factory using simulation at the very stage has been successful and has exercised with the simulation scenarios 1,2 and 3. This was achievable simply based on many assumptions as addressed above and with the help of the witness software that executes duties with the aid of input and output rules that need to be applied accordingly.

This paper presents a designed algorithm involves improvement of transferring data over Simple Object Access Protocol (SOAP). The aim of this work is to establish whether using SOAP in  exchanging XML messages has any added advantages or not. The results showed that XML messages without SOAP take longer time and consume more memory, especially with binary data

This study aims to examine the role the Libyan Stock Market (LSM) in Libyan Economic Growth from the perspective of brokers, employees and investors. A set of questionnaire are employed to identify the role of stock market in promoting economic growth, the problems inherent to LSM and the measures taken by the market to improve the contribution in economic growth. The findings indicate that the brokers, employees and investors agreed that LSM has significant potential and positively contribute to Libyan economic growth. The findings imply that in order to improve the contribution of LSM in economic growth, the Libyan Stock Market authority need to improve their policies to encourage more companies, especially main sectors companies such as oil, energy and communication, to contribute in the market. A set of regulations is also needed to develop LSM culture and to attract the local and foreign investors.
