Resilience metrics in the assessment of complex supply-chains performance operating under demand uncertainty

The design and planning of resilient supply chains is a major challenge due to the increasing complexity of these systems that operate in a global market and therefore are more exposed to disruptions. In the present work a design and planning model that integrates demand uncertainty is applied to five supply chain structures that are submitted to different types of disruptions. Disruptions are modelled in a probabilistic manner, resulting in the incorporation of two sources of uncertainty. Eleven indicators are considered to assess the supply chains’ resilience, which comprise network design, centralization and operational indicators. The goal is to provide managers what are expected operational impacts (measured by the operational indicators) by assessing the behavior of network and centralization indicators and their known resilience behaviors from the literature. A case study of a European supply chain is used to illustrate the methodology and a discussion on the results obtained is presented in order to conclude which main characteristics a manager should consider when designing and planning resilient supply chains.

The impact of JIT on capacity management: A case study and analysis

This article describes the production planning and control techniques used at Verbatim Computer Disk Company in Charlotte, NC. The factory operates by management policy on a 24 hours-per-day, 7 days-per-week, 363 days-peryear, basis as if it were a process industry. Production of discrete units, computer disks, follows repetitive manufacturing methods including the implementation of just-in-time JIT methods into an existing material requirements planning MRP system. Production is based on the actual customer orders received from Marketing for disks from both US customers and international markets. Marketing uses price adjustments in coordination with Production Planning to ensure the factories operate at 100 capacity and within predefined inventory levels. This article discusses the relationship between Marketing and Manufacturing which allows for the attainment of a process industry-like economies of scale for a line of discrete products. Key characteristics of the production planning and control system are identified as are the current operating problems.     

Dynamic decomposition of regional wage differentials in Korea

Using a Juhn–Murphy–Pierce (JMP) decomposition, this study analyses the dynamic changes in regional wage differentials between the Seoul Metropolitan Areas and other regions in South Korea. Data from the Korean Labor and Income Panel Study for three years (2000, 2004, and 2008) is used. JMP decomposition provides information about the components that explain changes in regional wage differentials over time. Between 2000 and 2004, the variations in observed and unobserved components are associated with counteracting effects on regional wage differentials. While changes in observed components contribute more to widen regional wage differentials, those in unobserved components narrow them. However, between 2004 and 2008, both observed and unobserved components move in the same direction to narrow regional wage differentials. Based on our empirical results, we discuss some policy implications.     

论中国共产党民族区域自治政策的形成

新疆南北疆区域经济差异的影响因素——基于Panel数据的实证研究

区域经济差异是多种因素综合作用的结果。以新疆维吾尔自治区1997—2009年的面板数据为基础,对新疆南北区域经济发展的影响因素进行了实证分析。研究结果表明,政策因素、工业化程度、人力资本和投资因素对新疆区域经济差异的形成均具有显著的影响,但这些因素对新疆南疆地区和北疆地区具有不同的影响方式和影响作用,其中财政收入和全社会固定资产投资对南疆地区经济增长的拉动作用较大,而工业生产总值、外贸进出口总额和劳动力数量对北疆地区经济增长作用明显。基于此,本文提出了缩小新疆南北疆区域经济差异的政策建议。     

Decision support for multi-family aggregate production planning

Aggregate production planning decisions are inter mediate range decisions that can have a significant impact on both productivity and profitability. In this paper, we examine an interactive computer-based method that provides decision support for the aggregate planner. The proposed approach combines the judgement of the planner with the optimization of subproblems to arrive at an effective solution for multi-family aggregate production planning problems. In the interactive approach, the planner exercises direct control over sensitive workforce levels and production capacities. A network flow sub-problem solver is used to generate optimal production plans and inventory levels given the user-specified production capacities. Decision aids are provided to help the planner achieve a cost-effective solution that is consistent with judgement concerning workforce levels. Computational testing on five test problems indicates that very cost-effective solutions can be obtained. The results of applying the interactive method to a real-world problem are also reported.     

Recent books on HRD

Abstract

The growing potential and need for knowledge and information have had a profound impact on Korea as it strives to develop strategies for national human resource development (NHRD). Within Korea, one strategy for developing NHRD is through regional efforts. However, there is little research regarding regional HRD (RHRD), in spite of the importance of such a focus. This article explores directions and policy-making strategies for RHRD in Busan. 1 1 Busan is often written as Pusan in English, though Busan is preferred in Korea.
