Abstract This paper proposes a multi-objective mixed-integer linear programming to model cold chain with complementary operations on hierarchical hub network. Central hubs are linked each other in the first level of network and star lower-level hubs. As for case study, different levels provide various refreshing or freezing keep perishable goods fresh along Disruption is formulated by considera...

Much fundamental research in computer science is driven by two complementary notions of beauty in programming, that arising from the structure of a program and that arising from the efficiency of an algorithm. As Lewin famously said, “there’s nothing so practical as good theory” [Marrow, 1984]. Decades of experience has borne out the remarkable efficacy of theory in improving the practice of pr...

Multiple transmission lines on a single right of way are commonly used by utilities. The phenomenon of common cause outages was first of all recognized by a Task Force from IEEE subcommittee [1]. The Task Force defined a common mode outage as "an event having a single external cause with multiple failure events, where the events are not consequences of each other". The closed form expressions f...

Answer Set Programming (ASP) has become an established paradigm for Knowledge Representation and Reasoning, in particular, when it comes to solving knowledge-intense combinatorial (optimization) problems. ASP’s unique pairing of a simple yet rich modeling language with highly performant solving technology has led to an increasing interest in ASP in academia as well as industry. To further boost...
