Reducing Food Scarcity: The Benefits Of Urban Farming, S.A. Claudell, Emilio Mejia

Journal of Nonprofit Innovation

Urban farming can enhance the lives of communities and help reduce food scarcity. This paper presents a conceptual prototype of an efficient urban farming community that can be scaled for a single apartment building or an entire community across all global geoeconomics regions, including densely populated cities and rural, developing towns and communities. When deployed in coordination with smart crop choices, local farm support, and efficient transportation then the result isn’t just sustainability, but also increasing fresh produce accessibility, optimizing nutritional value, eliminating the use of ‘forever chemicals’, reducing transportation costs, and fostering global environmental benefits.

Spare Parts On Demand Using Additive Manufacturing : A Simulation Model For Cost Evaluation., Stefan Jedeck

Electronic Theses and Dissertations

Little is known about the impact of additive manufacturing in the spare part supply chain. A few studies are available, but they focus on specific parts and their applications only. A general model, which can be adapted to different applications, is nonexistent. This dissertation proposes a decision making framework that enables an interested practitioner/manager to decide whether using additive manufacturing to make spare parts on demand is economical when compared to conventional warehousing strategy. The framework consists of two major components: a general discrete event simulation model and a process of designing a wide range of simulation scenarios. The goal …

Is It Time To Dump Your Vendor Management System?, Rihaz Z. Chughatta

Rihaz Z Chughatta

Most companies today have either implemented, or are exploring, some form of a Vendor Management System (VMS) to consolidate their external suppliers. Companies that sell a VMS point out that this system allows a Customer to get the most cost-effective solution for their needs within a certain category of suppliers; the “when suppliers compete, you win” mentality prevails. Some of the VMS even have performance metrics by which suppliers are measured and then rated in the system; thus making the case that not only does a VMS provide the most cost-effective, but also the best performing and most efficient solution …
