This paper considers the problem of production and preventive maintenance control in a stochastic manufacturing system. The system is subject to multiple uncertainties such as random customer demands, machine failure and repair, and stochastic processing times. A threshold-type policy is...

This paper considers the empty container management problem in a cyclic shipping route. The objective is to seek the optimal empty container repositioning policy in a dynamic and stochastic situation by minimising the expected total costs consisting of inventory holding costs, demand lost-sale...

This paper considers a manufacturing supply chain with multiple suppliers in the presence of multiple uncertainties such as uncertain material supplies, stochastic production times, and random customer demands. The system is subject to supply and production capacity constraints. We formulate the...
