This paper addresses a single item two-level supply chain inventory model considering deterioration during carrying of deteriorating from supplier’s warehouse to retailer’s as well in the warehouse. The assumes preservation technology prevent rate deterioration. An upper limit for investment has been set constraint model. maximizes profit per unit time, simultaneously calculated optimal order q...

Warehouse commissioning is a complex task in which a team of robots needs to gather and deliver items as fast and efficiently as possible while adhering to the constraint capacity of the robots. Typical centralised control approaches can quickly become infeasible when dealing with many robots. Instead, we tackle this spatial task allocation problem via distributed planning on each robot in the ...

In this paper, we propose a new approach to manage data distribution in a relationnal data warehouse environment. This approach deals with the dynamic data splitting on a set of interconnected machines. The data distribution that we consider is different from the “classical” one which depends on the data use. The distribution in our approach consists in splitting data when the machine reaches h...

The vehicle routing with pickups and deliveries (VRPD) problem is de6ned over a graph G=(V; E). Some vertices in G represent delivery customers who expect deliveries from a depot, and other vertices in G represent pickup customers who have available supply to be picked up and transported to a depot. The objective is to 6nd a minimum length tour for a capacitated vehicle, which starts at a depot...

Most data warehouse deployments are not prepared to scale automatically, although some applications have large or increasing requirements concerning data volume, processing times, data rates, freshness and need for fast responses. The solution is to use parallel architectures and mechanisms to speed-up data integration and to handle fresh data efficiently. Those parallel approaches should scale...

Choosing a suitable cross-border logistics mode is the foundation for e-commerce enterprises to achieve sustainable development. Based on an analysis of literature, modes are summarized as postal parcel, international express, overseas warehouse, and special line modes. Using multi-value set qualitative comparative (mvQCA) method explore factors formation paths selection enterprises, results in...

The classical problem of optimal transportation can be formulated as a linear optimization problem on a convex domain: among all joint measures with fixed marginals find the optimal one, where optimality is measured against a cost function. Here we consider a natural but largely unexplored variant of this problem by imposing a pointwise constraint on the joint (absolutely continuous) measures: ...

Logistics transportation between two countries presents some special challenges and issues for business organizations, because of the cost differentials between two countries regarding transporting, staffing, warehousing, etc. In this study, we consider a logistics problem experienced by a producer of electrical equipment, which needs to transport their products, which are produced in Mainland ...

ASRS is usually installed in a factory or warehouse to increase storage capacity, floor space utilization, labor productivity in storage operations and stock rotations etc. ASRS systems are custom-planned for each individual application, and they range in complexity from relatively small mechanized systems that are controlled manually to very large computercontrolled systems that are fully inte...

Data warehouse is the powerful tool in telecommunications industry for handling the massive amounts of data. It assists telecommunication companies in achieving a competitive advantage and higher profits. Theaim of this paper is to focus on data warehousing in telecommunication companies and why they need advanced data warehouse platforms and new technology. It compares traditional data warehou...
