In this paper, we studied a crane scheduling problem, i.e., the scheduling of RMCs to minimize the total weighted remaining work for the blocks in a terminal storage yard. The approach is a mix of planning method from AI and optimization methods based on MIP formulation. We implemented a DSS to incorporate both AI techniques and OR models. The experiments in simulation environment showed promis...

All voting protocols proposed so far, with the exception of a few, have the property that the privacy of the ballot is only computational. In this paper we outline a new and conceptually simple approach allowing us to construct a protocol in which the privacy of the ballot is unconditional. Our basic idea is to modify the protocol of Fujioka, Okamoto and Ohta[10], which uses blind signatures so...

product mix problem (pmp) is one of the most important and complicated problems in production systems. different approaches have been applied to solve this problem, among them, theory of constraints (toc) has been widely considered since 1990s. this paper develops a distinguished algorithm to solve product mix prob-lems that is efficient both in single and multi-bottleneck problems. at first, t...

A planning procedure to set the constant level of work in process (WIP) for each product type in a job shop operated under CONWIP control is developed. We model the job shop as a single chain multiple class closed queuing network. Given a specified product mix and a total WIP, a nonlinear program bounds the throughput of the network and optimizes the WIP mix. We identify the minimum total WIP t...

the poor orientation of the restaurants toward the information technology has yet many unsolved issues in regards to the customers. one of these problems which lead the appeal list of later, and have a negative impact on the prestige of the restaurant is the case when the later does not respond on time to the customers’ needs, and which causes their dissatisfaction. this issue is really sensiti...

The EU emissions trading scheme (ETS) taking effect in 2005 covers CO2 emissions from specific large-scale industrial activities and combustion installations. A large number of existing and potential future combined heat and power (CHP) installations are subject to ETS and targeted for emissions reduction. CHP production is an important technology for efficient and clean provision of energy bec...

Previous approaches to case-based planning often finds a similar plan case to a new planning problem to adapt to solve the new problem. However, in the case base, there may be some other cases that provide helpful knowledge in building the new solution plan. Likewise, from each existing case there may be only certain parts that can be adapted for solving the new problem. In this paper, we propo...

Introduction The Hong Kong Hospital Authority (HA) manages 41 publicly funded hospitals that serve approximately 90% of the seven-million population. The head office of HA is responsible for strategic planning, resources allocation, and monitoring performance of hospitals that are organized into seven geographical clusters. The head office is transforming its population-based internal resources...

In this paper, we report on the application of systems engineering in initiating synthesis a participatory planning support system (PSS) for sustainable regional planning. The SPADE approach is applied model-based fashion to define and link development goals (SDGs) urban policies co-creative multi-stakeholder environment. demonstrated through case study from interregional climate, land-use, tra...
