With consumer preferences reflecting the growing concern for the environment, retail delivery businesses are at the crossroads of implementing a sustainable operational and financial business model of delivering packages to customers. In this thesis, we will address the issue of sustainable packaging in retail delivery companies by evaluating the financial, environmental and operational viability of such strategies. The thesis will be limited to the downstream order fulfillment cycle from the retail delivery company to the customer. We will focus on three areas applicable to sustainable packaging. The first area is materials innovation where we will analyze alternative materials suitable for retail delivery packaging. The second area involves waste elimination through reducing packaging material use and reusing of packaging materials through a returnable tote program. Lastly, we will understand the implementation challenges to increase the success rate of the strategies mentioned earlier. / by Joshua Ng and Kendall Chow. / M.Eng.in Logistics

Most manufacturing conglomerates in the United States now have contract manufacturing plants in China. Because many of these US companies have implemented a variety of inventory reduction approaches, they are now faced with the expensive transportation of large numbers of low-weight, small- quantity shipments in international inbound transportation, transportation that covers the flows of goods from contract manufacturers (CMs) in China to original equipment manufacturers (OEMs) in the States. While there has been research on consolidation, little attention has been paid to international inbound freight consolidation, which provides a potential savings opportunity in international transportation by combining several small shipments into one large shipment. This paper examines how manufacturers in the United States can use freight consolidation in their international inbound transportation flow from CMs in China. It then explores a framework for designing inbound consolidation, focusing on how to implement inbound consolidation in the context of China's fast-evolving logistics industry. / by Yi Fang. / M.Eng.in Logistics

Thesis: M. Eng. in Logistics, Massachusetts Institute of Technology, Engineering Systems Division, 2015. / Cataloged from PDF version of thesis. / Includes bibliographical references (pages 71-72). / This thesis focuses on the study of the carrier-shipper relationships in the US trucking market. It uses data provided by a leading third party logistics (3PL) company to explore and determine whether a relationship exists between the prices charged by the carriers and the performance that they provide to the shippers. The performance metrics defined in the thesis are measured in three dimensions: on time pick-up, on time delivery, and acceptance ratio. The research uses ordinary least square (OLS) regression to study the effect of the performance parameters on the cost per load of a shipment. The research demonstrates that there is a mild relationship between on time delivery performance and price. With increase in on-time delivery performance, the price increases till a threshold is reached, beyond which it stabilizes. We found that a relationship exists between on-time pick-up and delivery. Since carriers who pick up late are able to deliver on time 80% of the times, the research could not find a direct relationship between on-time pick-up and price. The research also found that increased lane loyalty from a shipper to a carrier can lead to lower rates. / by Nane Amiryan and Sharmistha Bhattacharjee. / M. Eng. in Logistics

Thesis (M. Eng. in Logistics)--Massachusetts Institute of Technology, Engineering Systems Division, 2012. / Cataloged from PDF version of thesis. / Includes bibliographical references (p. 92-96). / Insourcing and vertical integration often allow companies to gain competitive advantage by exercising a greater degree of control over their supply chain. In the case of ABC Oilfield Services, insourcing the transportation of their products to offshore oil rigs at sea - a function currently provided by their customers - will increase asset velocity of their most important tools, and allow them to service more customers with fewer tools. This is an especially important consideration in light of the fact that the offshore drilling market will see double-digit growth in the coming years. This paper examines the effect of such increased asset velocity on Return on Assets (ROA). Using detailed historical data of ABC shipments of their biggest revenue-generating tools, we modeled both the status quo logistics system of ABC, and an alternative system based on sound insourcing assumptions. We then compared the projected ROA of the two scenarios in order to gain insights into the relationship between insourcing and its likely effect on ROA. We attempt to quantify the asset velocity benefits of insourcing, but also show the surprising result that increased asset velocity can have a negative effect on revenue under common pricing schemes. While there may be several other factors which help in ultimately making the decision to insource, the paper provides an important contribution in helping decision makers see the effects of insourcing in the oilfield services industry more clearly, and identifying the conditions under which insourcing will have the biggest benefit to ROA. / by Devjit Ghose and Kevin Murphy. / M.Eng.in Logistics

Thesis (M. Eng. in Logistics)--Massachusetts Institute of Technology, Engineering Systems Division, 2009. / Includes bibliographical references (leaves 96-99). / Humanitarian logistic organizations struggle to make strategic and tactical decisions due to their lack of resources, the unpredictability of humanitarian events and the lack of readily available information; the existing tools that assist optimal decision making require large amounts of precise information. As a consequence of all these challenges, most of the work in humanitarian logistics concentrates on the operational level that can only offer short term benefits. Alternatively, optimal strategic decisions maximize the resources of humanitarian organizations making them more flexible and effective in the long term; this directly impacts the ability to help the millions of people in need. This thesis presents a model that assists the largest humanitarian organization in the world, The World Food Programme, to make optimal strategic decisions. The model uses the Analytic Hierarchy Process, a multiple attribute decision tool that provides structure to decisions where there is limited availability of quantitative information. This methodology uses a framework that determines and prioritizes multiple criteria by using qualitative data and it scores each alternative based on these criteria. The optimal alternative will be the one that has the highest weighted score. This model solves the challenges that The World Food Programme, as any other humanitarian organization face when making complex strategic decisions. The model, not only works with easily acquired information but, it is also flexible in order to consider the ever-changing dynamics in the humanitarian field. / (cont.) The application of this model focuses on the optimization of warehouse locations for the World Food Programme in the Somali region of Ethiopia. However, this model can easily be scaled in order to be used in any other decision making process in the humanitarian field. / by Gina Malaver [and] Colin Regnier. / M.Eng.in Logistics

The certified thesis is available in the Institute Archives and Special Collections. / Includes bibliographical references (p. 61). / Although supply chain disruptions are inevitable, frameworks have been developed for addressing supply chain risks. These frameworks present methods on mitigating, reducing or managing the risks through different approaches such as multiple sourcing. The research presented here identified two factors that contribute to successful recovery from supply chain disruptions. One factor is efficient communication between stakeholders in a supply chain. The communication needs to be present before a disruption occurs to enable fast detection. After a disruption occurs efficient communications will help minimize confusion and provide clear understanding of the recovery effort between stakeholders. The other factor is the inventory position downstream of the disruption. In particular, the available days of supply downstream from the disruption relative to the length of the disruption are crucial to the ability of a supply chain to recover from the disruption without disturbing the continuity of supply. In response to the effect of the days of supply compared to the recovery time a simple model is developed for assessing supply chain risk for an enterprise that sells products defined through a bill-of-materials. / (cont.) The model takes into consideration the complexity of a product as more parts and more levels are added to the bill of material. The supply chain risk score metric permits comparison across products, companies and industries. The model is simple to apply by analyzing each part in bill-of-materials by a ranking system comparing the recovery time to the days of supply downstream from the disruption. The supply chain risk score is to be used in parallel with other supply chain metrics in order to determine the best approach in reducing risks to an enterprise. / by Theodore Doucakis. / M.Eng.in Logistics

Thesis (Ph. D.)--Massachusetts Institute of Technology, Engineering Systems Division, 2009. / Cataloged from PDF version of thesis. / Includes bibliographical references (p. 235-249). / Survivability is the ability of a system to minimize the impact of a finite-duration disturbance on value delivery (i.e., stakeholder benefit at cost), achieved through (1) the reduction of the likelihood or magnitude of a disturbance, (2) the satisfaction of a minimally acceptable level of value delivery during and after a disturbance, and/or (3) a timely recovery. Traditionally specified as a requirement in military systems, survivability is an increasingly important consideration for all engineering systems given the proliferation of natural and artificial threats. Although survivability is an emergent system property that arises from interactions between a system and its environment, conventional approaches to survivability engineering are reductionist in nature. Furthermore, current methods neither accommodate dynamic threat environments nor facilitate stakeholder communication for conducting trade-offs among system lifecycle cost, mission utility, and operational survivability. Multi-Attribute Tradespace Exploration (MATE) for Survivability is introduced as a system analysis methodology to improve the generation and evaluation of survivable alternatives during conceptual design. MATE for Survivability applies decision theory to the parametric modeling of thousands of design alternatives across representative distributions of disturbance environments. To improve the generation of survivable alternatives, seventeen empirically-validated survivability design principles are introduced. The general set of design principles allows the consideration of structural and behavioral strategies for mitigating the impact of disturbances over the lifecycle of a given encounter. / (cont.) To improve the evaluation of survivability, value-based metrics are introduced for the assessment of survivability as a dynamic, continuous, and path-dependent system property. Two of these metrics, time-weighted average utility loss and threshold availability, are used to evaluate survivability based on the relationship between stochastic utility trajectories of system state and stakeholder expectations across nominal and perturbed environments. Finally, the survivability "tear(drop)" tradespace is introduced to enable the identification of inherently survivable architectures that efficiently balance performance metrics of cost, utility, and survivability. The internal validity and prescriptive value of the design principles, metrics, and tradespaces comprising MATE for Survivability are established through applications to the designs of an orbital transfer vehicle and a satellite radar system. / by Matthew G.

Thesis (M. Eng. in Logistics)--Massachusetts Institute of Technology, Engineering Systems Division, 2010. / Cataloged from PDF version of thesis. / Includes bibliographical references (p. 69). / Partners in Health's (PIH) supply chain in Haiti has become strained over the past five years due to the organization's rapid growth. Under the current system, the majority of PIH's products are obtained through an annually placed order. All goods from this order are stored at the central warehouse in Cange, which acts as a hub, until those goods are needed at individual clinics. As annual orders increase in size to support PIH's expanding operations, the limited size of the central warehouse has become a constraint, making a change in current inventory policies necessary. In order to formulate revised inventory policies for PIH's Haiti operations, we developed a spreadsheet model that uses historical consumption data of drugs and medical supplies to forecast demand over the next three years. This demand data is then be used as input to run and compare the existing annual order policy with ordering policies with more frequent reviews. These inventory policies are then evaluated against the central warehouse size constraints to recommend an inventory policy better suited to meet PIH's needs. We find that more frequent orders drastically reduces warehouse space requirements while maintaining high service levels. It is hoped that PIH can continue to use this model to determine future inventory policy needs. / by Christine L. Heberley and Matthew F. Hoover. / M.Eng.in Logistics

Thesis (S.M.)--Massachusetts Institute of Technology, Engineering Systems Division, 2012. / Cataloged from PDF version of thesis. / Includes bibliographical references (p. 59-61). / Enterprises undergo transformation for more efficient and effective performance and growth. The Lean Enterprise Self Assessment Tool (LESAT) is a product of the Lean Advancement Initiative (LAI) and the Massachusetts Institute of Technology (MIT). This tool is used by many enterprises to assess strengths, areas of improvement, and the enterprise's readiness to change. LESAT has been designed for enterprises that offer products only, not services. However, many of the principles and methodologies apply to servicing existing systems, which is a growing industry trend both in the private and public sector. Servicing existing systems accounts for 70% of the United States Department of Defense weapon system's total life-cycle cost. Many enterprises offer services to support, maintain, and upgrade their products. Many enterprises also rely on core internal systems that must be maintained and upgraded such as airline reservation systems or supply chain logistics tools. An extension of LESAT for Servicing Existing Systems is proposed as an assessment tool toward lean effectiveness for products and services. Collaborations with the International Council on Systems Engineering (INCOSE) In- Service Systems Working Group; three aerospace and technology enterprises Boeing, Pratt & Whitney, and Raytheon; as well as review of the literature are used in capturing best practices for success in servicing existing systems. / by Tina Prabha Srivastava. / S.M.

"December 2012." / Includes bibliographical references (page 89). / With the ramp up of commercial spaceflight over the last decade with the assistance of the US Government and NASA, commercial spaceflight companies such as Space Exploration Technologies (SpaceX) and Orbital Sciences have taken significant strides in reducing the overall cost of space travel. The overall cost per launch goes far beyond the actual cost of the materials and labor associated with each launch vehicle, and must include all the political, environmental and social costs, which often amount to more than the actual cost of the vehicle itself. The main focus of my thesis is the Flight Termination System (FTS) which is the system used to terminate the flight of the launch vehicle in the event the vehicle veers off course or experiences any anomalies, which would impede its mission and cause a threat to human assets. Because of my work as the lead engineer of the FTS system at SpaceX, this thesis will mainly cover the system used at SpaceX. The FTS system is unique in that the approval of the system is as political and social as it is technical. Systems engineering is applied throughout the process of architecting, designing, testing, and manufacturing, where all stakeholders have a part in the success of each step of the product design. The key to the success of SpaceX lies in innovation, and as this thesis outlines, the FTS system has many innovative products and processes in place, including the establishment of many key relationships with stakeholders. / by Eugene Kwak. / S.M.in Engineering and Management
