A proactive environmental strategy (PES) serves as an impactful and effective way to alleviate a firm's adverse environmental impact, and environmental regulations are widely recognized as primary and crucial for promoting a PES. However, most studies in the PES field overlook the pivotal role of external knowledge acquisition and social media capability. Therefore, we have developed a theoretical...Show More
As fresh product e-commerce experiences exponential expansion, the delivery of fresh products which are perishable is becoming a large part of road freight transportation. Transporting perishable products is a challenging task as it is difficult to preserve their nutritional value and freshness. To keep the freshness of such products in delivery, efficient transportation is critical. Besides, cust...Show More
Growing consumer privacy concerns have led firms, such as HP, to introduce trade-in services with privacy protection, while others, such as ASUS, continue to provide trade-in services without such protection. In this article, we focus on two competitive firms to explore whether they should provide a trade-in service with privacy protection. We categorize replacement consumers into two groups based...Show More
The effective disposal of healthcare waste is a highly concerned issue. Healthcare waste collection poses transport risks and temporary storing risks, and the deliberation undertaken by decision-makers concerning waste collection entails potential scenario wherein some hospitals have not yet submitted their service requests and may submit their requests during the healthcare waste collection proce...Show More
The popularity of online shopping places higher demands for e-tailers’ service, especially the return process. Cooperative-return-to-store (CRS), where an e-tailer's merchandise can be returned to another retailer's stores, seems to provide a panacea for e-tailers to improve return flexibility and save on return handling costs. However, current practices indicate that only a limited number of e-ta...Show More
Lane reservation strategies are widely used to ensure the right of way for eco-friendly vehicles and encourage people to green their commute. In most lane reservation problems (LRPs), the parameters underlying the system traffic conditions (e.g., vehicle speed and traffic flow) cannot be effectively specified. This paper addresses a new dynamic lane reservation problem (DLRP), which aims to optimi...Show More
This article investigates the impact of information sharing on supply chain performance when considering the product loss in e-commerce. By characterizing four information sharing mechanisms, we analyze the optimal information sharing decisions on bullwhip effects and inventory costs in near/far-distance e-commerce contexts. The analytical results reveal the vital significance of product loss info...Show More
As a consequence of expedited urban construction, large quantities of wastes are shipped every day. Because of the excessive pursuit of economic benefits by muck truck drivers and unreasonable transportation route choices, the accident rates of these drivers continue to increase. It is very important to optimize the safe transportation routing of muck trucks. In this paper, a safe transportation r...Show More
The robustness of project schedule plays an important role for the smooth execution of project under uncertain conditions. This paper studies the proactive project scheduling problem with stochastic activity durations and flexible resource constraints. The objective is to schedule the starting times of the activities in a reasonable way so as to maximize the robustness of project schedule under th...Show More
This paper addresses the resource-constrained project proactive scheduling problem with uncertain activity durations considering information handling cost. An proactive optimization model is proposed to derive the information handling cost and the proactive starting time of each activity decisions that minimize the total uncertainty cost of a proactive schedule, which includes an information handl...Show More
Time/cost trade-off problems is a well-known project scheduling problem. These years many researchers begin to focus on the project scheduling under uncertainty, such as resource idleness, high inventory and missing deadlines. This paper addresses a time-cost-robustness trade-off project scheduling problem with multi-mode under uncertainty. A multi-objective model of three objectives is constructe...Show More
In this paper, we investigate the resource-constrained project scheduling problem with resource transfer times under uncertain environment, aiming to generate robust baseline schedules that will be as stable as possible during project execution. In this problem, resource transfer times are taken into account, and the objective function is solution robustness maximization. As the problem is proved ...Show More
In general, reverse logistics network design has been driven by a need to reduce costs and to improve customer service without considering its environmental impact. In this paper, we address a reverse logistics network design problem regarding carbon emission. The problem is formulated as a bi-objective, mixed-integer, and nonlinear programming model under various operation technologies and transp...Show More
Proactive scheduling aims at the generation of robust baseline schedules, which has been studied for many years with the assumption that activity splitting is not allowed. In this paper, we focus on the proactive resource-constrained project scheduling problem in which each activity can be split at discrete time instants under the constraints of a maximum number of splitting and a minimum period o...Show More
As a consequence of industrial development, large quantities of hazardous materials are shipped everyday. Most related studies consider the risks as fixed weights on edges. However, the loads of the vehicles are important factors about the risks. Thus, considering the risks as fixed parameters cannot reflect actual practice. In addition, the vehicle routing models in previous studies simultaneousl...Show More
This paper investigates the project scheduling problem to minimize the maximum cash flow gap of contractors under random activity duration. A comprehensive optimization model with time buffers added to the baseline schedule by project proactive scheduling and the schedule adjustment cost determined by project reactive scheduling is constructed to manage disruptions caused by the randomness of acti...Show More
As a by-product of industrial development, large quantities of hazardous materials are shipped in the transportation network every day. The risk of transporting hazardous materials is an important consideration in transportation planning. Vehicle routing models in previous studies simultaneously minimized the transportation cost and the total risk. However, simply evaluating the total risk of a fl...Show More
This paper investigates the difference in bullwhip effects in online and offline retail supply chains, offering insights into how frequent price discounts in e-commerce influence the bullwhip effect in the online retail supply chain. We consider a two-level online retail supply chain with a manufacturer and an online retailer in which the demand faced by the retailer is price sensitive and based o...Show More
In recent years, the ever-rising return streams for repair service have forced the electronics manufacturers to expand their reverse logistics capacities. However, most existing papers on the reverse logistics network design neglected the time sensitivity of the return flows. Moreover, most of these investigations were primarily concerned with the single objective problems of either minimizing the...Show More
There are more than thirty years that the capacitated dynamic lot sizing problem has appeared which is more and more interested by researchers around the world. With the rapid development of environment problems in production process, lots of manufacturing companies focus on products return and remanufacturing. In order to accord with practical demand, this paper based on Richterpsilas remanufactu...Show More
