The cap-and-offset regulation is a practical scheme to lessen carbon emissions.The retailer selling fresh products can adopt sustainable technologies to lessen greenhouse gas emissions.We aim to analyze the optimal joint strategies on order quantity and sustainable technology investment when the retailer faces stochastic market demand and can only acquire the mean and variance of distribution information.We construct a distributionally robust optimization model and use the Karush-Kuhn-Tucker(KKT)conditions to solve the analytic formula of optimal solutions.By comparing the models with and without investing in sustainable technologies,we examine the effect of sustainable technologies on the operational management decisions of the retailer.Finally,some computational examples are applied to analyze the impact of critical factors on operational strategies,and some managerial insights are given based on the analysis results. 展开更多

In this paper, considering a scenario in which there are two quality levels of fresh products and introduction of consumer utility function, we studied the optimal ordering and pricing strategies under certain quantity. Our results showed that, facing the two quality levels of fresh products, retailers would not benefit from sales of lower quality of fresh products with the deterministic demand. In the pursuit of profit maximization, the initial order quantity is smaller than the potential demand for market. 展开更多

[Objectives]To compare anti-inflammatory and analgesic effects of fresh and dry products of Zhuang medicine Asystaia gangetica on mice.[Methods]Experiments were performed using glacial acetic acid to increase capillary permeability in mice,cotton ball to cause granulomatous formation in mice,xylene to cause auricular swelling in mice,chronic inflammation,and acetic acid-induced pain and hot-plate pain.Besides,the anti-inflammatory and analgesic effects of fresh and dry products of A.gangetica on mice were observed with the indicators of capillary permeability in the abdominal cavity,swelling rate of auricles,cotton ball granulomas and writhing times,and thermal pain threshold.[Results]Fresh products of A.gangetica had significant inhibitory effects on peritoneal capillary permeability increase in mice induced by glacial acetic acid,mouse auricle swelling induced by xylene,and mouse granuloma formation induced by cotton balls.Dry products of A.gangetica also significantly inhibited the auricle swelling in mice induced by xylene,but the effect intensity was weaker than that of fresh products.In addition,dry products of A.gangetica showed a certain tendency to inhibit the increase of capillary permeability in the abdominal cavity of mice induced by glacial acetic acid.In the analgesic experiment,both fresh and dry products of A.gangetica showed better analgesic effect,but caused pain on the hot plate,and the analgesic effect time of fresh products was shorter than that of dry products.[Conclusions]Both fresh and dry products of Zhuang medicine A.gangetica have certain anti-inflammatory and analgesic effects. 展开更多

Link-up between farmers and supermarket is a new move adopted actively by the current government, conducive to consumers, farmers and circulation enterprises. At present, link-up between farmers and supermarket is launched in China's 15 provinces and cities, which will set off the revolution in the field of agricultural circulation. Based on the current situation of link-up between farmers and supermarket and the existing problems, we put forth the following recommendations: promoting the quality of farmers' cooperative organizations; establishing the logistics center of fresh agricultural products; using economies of scale to reduce the fresh logistics costs; improving the operation and management level of fresh agricultural products in supermarket. 展开更多

In recent years,Guangxi realized consecutive bumper harvests in fresh agricultural products,leading increase of logistics demand;logistics infrastructure begins to take shape,and logistics of fresh agricultural products takes on diversified development form with wholesale market as main form. However,traditional fresh agricultural products are not selling well and it lacks construction of supply chain; the construction of logistics information system for fresh agricultural products lags behind; organizational level of production and operation of fresh agricultural products is low. Through analyzing current situations and existing problems of logistics of Guangxi fresh agricultural products in the new period( 21 st century),this paper came up with recommendations for developing logistics of fresh agricultural products of Guangxi. Government should increase policy and financial support,build and manage supply chain of fresh agricultural products,accelerate construction of logistics information system for agricultural products,and improve organizational level of logistics of fresh agricultural products,to ensure healthy development of logistics of fresh agricultural products in Guangxi. 展开更多

The low efficiency and high cost of fresh agricultural product terminal distribution directly restrict the operation of the entire supply network.To reduce costs and optimize the distribution network,we construct a mixed integer programmingmodel that comprehensively considers tominimize fixed,transportation,fresh-keeping,time,carbon emissions,and performance incentive costs.We analyzed the performance of traditional rider distribution and robot distribution modes in detail.In addition,the uncertainty of the actual market demand poses a huge threat to the stability of the terminal distribution network.In order to resist uncertain interference,we further extend the model to a robust counterpart form.The results of the simulation show that the instability of random parameters will lead to an increase in the cost.Compared with the traditional rider distribution mode,the robot distribution mode can save 12.7%on logistics costs,and the distribution efficiency is higher.Our research can provide support for the design of planning schemes for transportation enterprise managers. 展开更多

The use of Fresh Cut Products (FCP) allows food service units to offer a greater variety of menus, reducing costs and minimizing cross contamination. Few food units in Portugal are adopting FCP, since these products are viewed as being more expensiveand are regarded as less natural and easily perishable.The present study aims to identify and analyze the level of awareness of food service operators in respect to FCP. Approximately 90% of food handlers referred the use of FCP at their workplace, pointing as the main advantages for using them the less time spent on preparation (58.6%), the variety (55.9%) and the convenience (55.9%). Reasons for not using them were doubtful origin (91.7%), price (66.7%) and being a possible threat to their jobs (58.3%). In spite of recognizing the advantages of using FCP, most of food handlers (77.2%) prefer traditional products. Traditional products were preferred by food handlers with lower educational level, working at schools and performing functions of kitchen helper. FCP were chosen by younger food handlers, with higher educational level. It seems necessary to promote a demystification of this category of products near food service managers and employees, explaining the best way and advantages of using FCP at institutional food services in terms of safety, cost and quality. 展开更多
