Key issues of the application of modelling and simulation for the management of the Malaysian Kelang Container Terminal are discussed. The aim of the investigation is to improve the logistics processes at the port. The model simulates all processes required to operate the seaport efficiently and provides detailed statistics on the seaport through‐put and utilisation characteristics with a high level of accuracy. The quay cranes allocation, the resources allocations and the scheduling of the different operations are modelled to maximise the performance of the port. The assignment of prime movers to transport containers to a yard area is also considered.

Emergency departments open 24 hours every day and may receive patients at any time most unexpectedly.Adequate resource planning to meet the various demands in emergency departments is arguably amongst the most critical challenges faced by hospital administrators due to the complexity of the system and diverse patient flows.In this paper, we present a computer simulation model to evaluate resource utilization among personnel and physical resources in a typical emergency department (ED) of a government hospital in Malaysia.The model allows administrators to see patient movement flows as well as how these flows are affected by resource capacity level in the ED.The use of this simulation model helps to evaluate ED operations, provides useful insight for possible areas of improvement, and directs the allocation of specific resources for maximal impact. Three scenarios were tested to find out the impact of patient surge on ED performance measures. Results from the scenarios show that a 30% increase of attendances according to triage zones affects most of the performance measures.In addition, medical assistants are the critical resources with average utilization greater than 70%.
