This paper aims to analyze decision-making problems in Groupage Systems from a complexity-science perspective. Therefore, the idea of Complex Adaptive Logistics Systems (CALS) and its inherent organization principle of autonomous co-operation and control will be presented. Furthermore, Groupage systems as a way to implement collaborative transportation planning will be introduced and, in combin...

Multitask emergency logistics planning is a complex optimization problem in practice. When disaster occurs, relief materials or rescue teams should be dispatched to destinations as soon possible. In nutshell, the can described an of multipoint-to-multipoint transportation delivery given multimodal traffic network. this study, network considered for planning, and mixed-integer programming (MIP) ...

We present a set of planning domains and problems that have been used as benchmarks for the fifth International planning competition. Some of them were inspired by different types of logistics applications, others were obtained by encoding known problems from operation research and bioinformatics. For each domain, we developed several variants using different fragments of PDDL3 with increasing ...

The current paper uses a scenario from logistics to show that modern heuristics, and in particular particle swarm optimization (PSO) can significantly add to the improvement of staff scheduling in practice. Rapid, sub-daily planning, which is the focus of our research offers considerable productivity reserves for companies but also creates complex challenges for the planning software.

This paper synthesizes general constraint satisfaction and classical AI planning into a theory of incremental change that accounts for multiple objectives and contingencies. The hypothesis is that this is a new and useful paradigm for problem solving and re-solving. A truth maintenance-based architecture derived from the theory is useful for contingent assignment problems such as logistics plan...

Crops are harvested by performing a series of operations with harvesting vehicles in the field. The harvest operation is performed with combines (harvesters). Supporting logistical activities of transferring and transporting harvest (grain) from the field to the farm are carried out with the help of tractors. This research focuses on detailed logistics planning of various infield harvest operat...

Logistics distribution and movements planning involves developing an efficient plan to move all of the required supplies, equipment and personnel to desired locations in a timely manner. It is an inherently difficult problem to solve and given the complexity of the problem, scenarios of a realistic size can take a significant amount of time to compute. A greedy distribution algorithm has been c...

In order to ensure that future human lunar and Mars exploration programs are both affordable and sustainable, it is essential to consider the impact of logistics, especially for long-duration and multiple mission campaigns. It is important that logistics be taken into account at an early stage in the design process, because the exploration architecture and vehicle design undoubtedly impact logi...

Based on the theory of complex network, this paper focuses on the planning of logistics nodes for strategic supply chain. I propose a practical mathematical modeling framework that simultaneously captures many practical aspects but still understated in the existing literatures of network planning problems. Moreover, capacity expansion and reduction scenarios are also analyzed as well as modular...

With people’s increasing concern about food safety, cold-chain logistics distribution centre is playing an important role in preventing food from going bad. Now cold-chain logistics distribution centres have the problems of too much transportation, low degree of automation, unreasonable layout planning, complex distribution process etc. It is important to solve these problems in order to achiev...
