Abstract
The study addressed the integrated problem of transport-storage in economic institutions. it provides general proposals to support designers in constructing systems. it uses closed queueing network and accompanying algorithms in modeling and solving such a problem. proposed software creates plans and gradually optimizes it until gets acceptable indicators. Port-Said cargo and container handling company was selected as an experimental case where facilities’ abilities and working limitations were studies for gaining three benefits (achieving fair workload distribuion amonge quay cranes, maximizing the demand time on yard cranes and determining the lowest numbers of tractors). results proved the efficiency of such system.
