This study presents a novel problem called green travelling salesman problem (GTSP), an extension of the classical travelling salesman problem (TSP). Proposed GTSP considers not just for the route distance, also accounts emitted CO2, consumed fuel, travelling times/speed and their costs with a more comprehensive objective function. The aim of this study is to shed light on the trade-offs betwee...

We address a real-world optimization problem: the scheduling of a Bank Information Technologies (IT) staff. This problem can be defined as the process of constructing optimized work schedules for staff. In a general sense, it requires the allocation of suitably qualified staff to specific shifts to meet the demands for services of an organization while observing workplace regulations and attemp...

This paper provides a framework in order to incorporate reliability issue as a sign of disruption in distribution systems and partial covering theory as a response to limitation in coverage radios and economical preferences, simultaneously into the traditional literatures of capacitated facility location problems. As a result we develop a bi-objective model based on the discrete scenarios for e...

We present a library of implemented HPSG analyses for argument optionality based on typological studies of this phenomenon in the world’s languages, developed in the context of a grammar customization system that pairs a crosslinguistic core grammar with extensions for non-universal phenomena on the basis of user input of typological properties. Our analyses are compatible with multiple interse...

W ith an ever-declining number of papers written in languages other than English, the idiom of Shakespeare is, today more than ever before, the international language of science [1,2]. In 2014, according to PubMed’s language filter, 95.4% of life science publications retrieved by the search engine were written in English, in line with the trend of the last several decades [1,2]. Today, among th...

This paper presents a novel, mixed-integer programming (MIP) model for the quay crane (QC) scheduling and assignment problem, namely QCSAP, in a container port (terminal). Obtaining an optimal solution for this type of complex, large-sized problem in reasonable computational time by using traditional approaches and optimization tools is extremely difficult. This paper, thus, proposes a genetic ...

Natural disasters occur frequently in recent years, causing huge casualties and property losses. Nowadays, people pay more and more attention to the emergency logistics problems. This paper studies the emergency logistics problem with multi-center, multi-commodity, and single-affected-point. Considering that the path near the disaster point may be damaged, the information of the state of the pa...
