We study a bi-objective covering problem stemming from real-world application concerning the design of camera surveillance systems for large-scale outdoor areas. It is in this prohibitively costly to surveil entire area, and therefore necessary be able present decision-maker with trade-offs between total cost portion area that surveilled. The can stated as set two objectives, describing constra...

Software maintenance is an important step in the software lifecycle. module clustering a HHMO_CF_GDA optimization problem involving several targets that require minimization of coupling and maximization cohesion. Moreover, multi-objective involves assembling specific group modules according to cluster criteria. classifies into different clusters enhance process. A structure with low high cohesi...

Aiming towards a sustainable supply chain, Physical Internet (PI) has been presented as global logistics network with standardized PI-containers. PI-nodes, and more specifically PI-hubs, are one of the key elements concept. This paper focuses on optimising operations in Road-Road PI-hub, which was not addressed literature. PI-hubs designed to transfer PI-containers between suppliers’ customers’...

The main aim of randomized search heuristics is to produce good approximations of optimal solutions within a small amount of time. In contrast to numerous experimental results, there are only a few theoretical results on this subject. We consider the approximation ability of randomized search for the class of covering problems and compare single-objective and multi-objective models for such pro...

Scheduling for job shop is very important in both fields of production management and combinatorial op-timization. However, it is quite difficult to achieve an optimal solution to this problem with traditional opti-mization approaches owing to the high computational complexity. The combination of several optimization criteria induces additional complexity and new problems. In this paper, we pro...
