We obtain gas-phase homolytic Al–H bond dissociation enthalpies (BDEs) at the CCSD(T)/CBS level for a set of neutral aluminium hydrides (which we refer to as AlHBDE dataset). The BDEs in this dataset differ by much 79.2 kJ mol−1, with (H2B)2Al–H having lowest BDE (288.1 mol−1) and (H2N)2Al–H largest (367.3 mol−1). These results show that substitution least one –AlH2 or –BH2 substituent exerts f...

This paper models and solves the scheduling problem of cable manufacturing industries that minimizes total production cost, including processing, setup, storing costs. Two hybrid meta-heuristics, which combine simulated annealing variable neighbourhood search algorithms with tabu algorithm, are proposed. Applying some case-based theorems rules, a special initial solution optimal setup cost is o...

The present study is concerned with the simultaneous optimization of the size of components and the arrangement of connections for performance-based seismic design of low-rise SPSWs. Design variables include the size of beams and columns, the thickness of the infill panels, the type of each beam-to-column connection and the type of each infill-to-boundary frame connection. The objective functio...

This paper primarily presents a comprehensive dynamic layout design model which integrates layout and transportation system design via considering more realistic assumptions, such as taking account of fixed-position departments and distance between departments that endanger each other. In addition, specific criteria such as capacity, cost and reliability of facilities are considered in transpor...

This paper addresses a rollon–rolloff waste collection vehicle routing problem which involves large containers that collect huge amounts of waste from construction sites and shopping malls. In this problem, vehicles could only move one container at a time between customers’ locations, a depot, a disposal center, and a recycling center site. Other than a disposal center, a recycling ...

Here, a mixed-integer linear programming model is developed to represent transportation system of students traveling from/to university campus. The concept ridesharing used and the mechanism combinatorial auctions incorporated within routing-based model. mathematical based on vehicle routing problem along with appropriate constraints accommodating features that express auction clearing phase. A...
