As communication technologies advance, millimeter wave (mmWave) signals have been widely used, leading to the rise of massive multiple input multiple output (MIMO) systems. However, the huge resource consumption cost by all-digital beamforming limits its application in MIMO. Thus, the hybrid beamforming technology raise much attention since its efficiency and low cost. This letter proposes an inte...Show More
To reasonably allocate shared resources (SRs) in project portfolios (PP) and realize PP's maximal benefits, in this article, we propose a hybrid SRs allocation model based on system dynamics (SD) and discrete event simulation (DES). Unlike previous resource allocation methods that solely consider project level benefits, the proposed model simultaneously considers the benefits at both project and p...Show More
A novel model is proposed for optimal project portfolio selection (PPS). Different from previous PPS methods that consider the interdependence, interaction, or synergy relationships among projects, this article considers the cascading failure process caused by these relationships. Specifically, we first construct a PP network (PPN) and determine the initial load and capacity of the projects (nodes...Show More
In the context of low-carbon and green development, aiming at the question of green development level of large automated container ports, a new multidimensional index system is constructed to evaluate the green development level of large automated container ports which based on the DPSIR research framework and principle of sustainable development, comprehensively considering the five key evaluatio...Show More
With the development of the times and the change of people's lifestyles, people are opting to order food online. For the perishable food, the delivery time and quality requirements are getting stricter. However, in practice, the production of perishable food mostly relies on experience decision-making, and the distribution mainly relies on takeaway riders, which affects the efficiency of the syste...Show More
The petrol station replenishment problem (PSRP) refers to the process of transporting petroleum products from oil depots to petrol stations via tank trucks. It mainly consists of two parts: allocating petroleum products to tank trucks and planning the travel route of each truck. In this study, we examine a new variant of PSRP by considering a multi-depot vehicle routing problem with open inter-dep...Show More
This paper investigates a multi-period closed-loop food supply chain planning problem. Returnable transport items are used to ship food products from a single manufacturer to multiple retailers. Food quality deteriorates over periods. Both economic and environmental issues are taken into consideration. For the problem, we propose a bi-objective mixed integer linear program to simultaneously maximi...Show More
This paper aims to study a new form of facility layout problem, in which the building has already been constructed and the specific room layout inside has been determined. Unlike the traditional facility layout problem, what we take into account is how to assign a certain number of rooms to a given number of departments with the purpose of maximizing the utilization rate of the rooms. This is equi...Show More
