An Evaluation of the Critical Success Factors in Sustainable Food Supply Chains in Developing Countries

Food is one of the biggest industries in developed and underdeveloped countries. Supply chain sustainability is essential in established and emerging economies because of the rising acceptance of cost-based outsourcing and the growing technological, social, and environmental concerns. The food business faces serious sustainability and growth challenges in developing countries. A comprehensive analysis of the critical success factors (CSFs) influencing the performance outcome and the sustainable supply chain management (SSCM) process. A theoretical framework is established to explain how they are used to examine the organizational aspect of the food supply chain life cycle analysis. This study examined the CSFs and revealed the relationships between them using a methodology that included a review of literature, interpretative structural modeling (ISM), and cross-impact matrix multiplication applied in classification (MICMAC) tool analysis of soil liquefaction factors. The findings of this research demonstrate that the quality and safety of food are important factors and have a direct effect on other factors. To make sustainable food supply chain management more adequate, legislators, managers, and experts need to pay attention to this factor. In this work. It also shows that companies aiming to create a sustainable business model must make sustainability a fundamental tenet of their organization. Practitioners and managers may devise effective long-term plans for establishing a sustainable food supply chain utilizing the recommended methodology.

异构平台要素协同理论方法研究

要素协同是协同作战发展的必经之路,杀伤链的动态重构是其典型特征.本文针对平台协同难以满足复杂作战任务需求的问题,提出了异构平台要素协同的解决思路和理论方法.首先分析了要素协同关系复杂性、协同能力不确定性两个难点问题;其次基于反馈机制的可重构架构对复杂作战网络进行建模,提出了杀伤链算子的要素动态重构、协同序参量的效能定量评估方法;最后基于仿真场景实现杀伤链的动态构建与重构,可指导要素协同的算法设计与工程实践.

基于Lagrange算法的集群式供应链跨链订单并行配置优化

为研究客户订单在供应链间的协作处理机制,考虑集群式供应链环境下基于两条单链进行柔性动态订单配置的情形,建立订单并行配置条件及基本模型。考虑链间横向合作现实,扩展构建订单跨链并行配置模型,用以机动处理能力内和能力外的跨链订单。基于Lagrange算法进行求解。仿真分析发现,跨链下的订单配置策略比无跨链情形更具弹性,在保证生产能力充分负荷的同时减少了订单拒绝风险。同时还发现,订单拒绝机会成本系数和跨链订单生产成本系数对订单配置有重要影响,这两个参数的组合中存在一个临界点,集群式供应链可通过临界点演化出来的组合,设计出对优先订单和跨链订单的接受决策及其生产规划,从而使客户满意度和总利润达到最优。

三维弹性机织物的结构与织造

为了顺利织造三维弹性机织物,分析了三维弹性机织物的结构特点,认为按照确定织物的层数及外观形态、绘制织物的经向截面图、确定引纬顺序、设计穿综图和穿筘图、确定纹板图和组织图、计算总经根数的顺序,可实现顺利织造。并指出在织造过程中应选择合适的纱线、采用分层定位装置、控制吊综高度、采用多织轴、采用全开梭口、采用多只梭子织造等。

Benders算法下集群式供应链多级订单柔性决策模型

针对大批量定制化的客户订单,供应链企业在进行订单决策时,往往缺少对不同特点订单的分级分类,导致部分超出负荷的有效订单缺乏柔性合作渠道,给供应链带来潜在的运作风险。为此,以产业集群为背景,通过分析客户订单的特点和层级,建立单级无链间协作的订单决策基本模型;在此基础上,考虑多供应链横向跨链协作影响因素,拓展构建了基于集群式供应链的多级跨链订单决策模型,以大批量动态处理客户订单的层级分类及柔性配置,实现订单的在线实时决策,并设计Benders分解算法求解。数值计算和仿真分析表明,多级订单决策比单级订单决策更具柔性;同时,客户满意因子和跨链协作因子对订单跨链决策具有阈值效应,而基于阈值点的组合策略进一步验证了多级订单柔性决策的现实可行性。
