Modern domain-independent heuristic planners evaluate their plans on the basis of their length only. However, in real-world problems there are other criteria that also play an important role, such as resource consumption, profit, safety, etc. This paper extends the GRT planner, an efficient domain-independent heuristic state-space planner, with the ability to consider multiple criteria. The heu...

tower cranes are major and expensive equipment that are extensively used at building construction projects and harbors for lifting heavy objects to demand points. the tower crane locating problem to position a tower crane and supply points in a building construction site for supplying all requests in minimum time, has been raised from more than twenty years ago. this problem has already been so...

In this paper, the gate matrix layout is formulated as a planning problem where a "plan" (the solution steps) is generated to achieve a "goal" (the gate matrix layout) that consists of subgoals interacting each other. Each subgoal corresponds to the placement of a gate to a slot. or to the routing of a net connecting gates. The interaction among subgoals is managed with two AI planning techniqu...

Memetic algorithms (MAs) are, at present, amongst the most successful approximate methods for combinatorial optimization. Recently , their range of application in this domain has been extended, with the introduction of several MAs for problems possessing multiple objectives. In this paper, we consider two of the newest of these MAs, the random directions multiple objective genetic local searche...

This paper describes the application of multiobjective heuristic search algorithms to the problem of hazardous material (hazmat) transportation. The selection of optimal routes inherently involves the consideration of multiple conflicting objectives. These include the minimization of risk (e.g. the exposure of the population to hazardous substances in case of accident), transportation cost, tim...

There is a growing global interest in low/zero carbon buildings in response to the increased CO2 in the atmosphere, nearly half of which comes from building energy consumption. Buildings are built for a considerably longer lifespan and enhancing energy efficiency in buildings can play a significant role in reducing CO2 emissions. Energy efficiency features need to be incorporated at the earlies...

Plant layout design is related to the location of facilities (e.g. machines, departments) in a plant. They are known to greatly impact the system performance. Numerous research works related to facility layout have been published. A few literature reviews exist, but they are not recent or are restricted to certain specific aspects of these layout design. The literature analysis given here is re...
