Reverse Supply Chain

Supply chains must align their goals with those of sustainable development and modify practices that compromise the ability of future generations to meet their needs. One of the practices that must be modified is the generation of large volumes of Municipal Solid Waste [MSW] that results from a linear production process. Traditional supply chains are jointly responsible for this problem. A circular production process in which the consumption of natural resources is reduced is possible through Reverse Supply Chains. For this, it is necessary to have tools for the sustainable design of MSW recovery networks. The objective of this work is to propose a systems engineering procedure that serves this purpose. The main contribution is the proposal of an explicit and concrete way to conceptually design RSC, useful for decision makers. The procedure consists of four interconnected stages that constitute an interactive system that allow the design from the problem formulation to its validation. The procedure is applied to design a RSC for MSW in the Mexican municipality of Netzahualcoyotl. The designed RSC can move a volume of 420 tons of MSW per day in an urban area of just 50 square kilometers. The scope of this work is a conceptual design that still requires field testing to validate the estimated results and make a feedback process that allows strengthening the conceptual design procedure.

<p>Acts of terrorism are crimes and serious violations of human rights, also the threat of violence that can cause mass casualties and destruction of vital strategic objects. This is an urgent threat that needs to be prepared by designing a bomb detector conceptual design as anticipation of the threat of terrorism in public services. This study aims to obtain operational requirements and conceptual design of bomb detectors as detection of terrorism threats in public services. This study uses a mixed-method with a systems engineering approach and a life cycle model to produce a technological design. The results of operational requirements are sensors, standards, artificial intelligence, integration capability, reliability, calibration mode, portable, and easy to maintain. The configuration design is divided into three stages, namely, 1) sensors including a camera security surveillance system vector image, metal detectors, explosive detectors, and A-jamming; 2) as a processing device, processes an order with the help of an artificial intelligence system; and 3)  a security computer (surveillance), early warning, and mobile information to provide information to related agencies, especially the anti-terror unit.</p>

With a renewed global focus on anti-submarine warfare (ASW), the United States Navy will increasingly rely on unmanned underwater vehicle (UUV) technology to serve as a cost-effective force multiplier. Modern UUV development necessitates a uniquely constrained, iterative approach to the traditional submarine design spiral. Considering a broad spectrum of customer-generated requirements, the UUV conceptual design process applies the best practices of naval architecture, marine engineering, ocean engineering, systems engineering, and submersible design. This paper provides an assessment of the traditional approach to the UUV design and development process. Specifically, this paper analyzes the design philosophy for modern UUVs, provides a design framework for the UUV conceptual design process, and details specific recommendations to encourage innovation in the subsea realm.

Operational Processes

In the past, many companies were concerned with managing activities primarily along the traditional supply chain to optimize operational processes and thereby economic benefits, without considering new economic or environmental opportunities in relation to the reverse supply chain and the use of used or reclaimed products. In contrast, companies are now showing increased interest in reverse logistics and closed loop supply chains (CLSCs) and their economic benefits and environmental impacts. In this chapter, our focus is the study of remanufacturing activity, which is one of the main recovery methods applied to closed loop supply chains. Specifically, the authors investigate and evaluate strategies for effective management of inventory control and production planning of a remanufacturing system. To pursue this objective, they model a production and inventory system for remanufacturing using the System Dynamics (SD) simulation modeling approach. The authors primary interest is in the returns process of such a system. Case studies will be referred to in this chapter to support some of the findings and to further validate the developed model.
