Background: Challenges with food loss in perishable food supply chains (PFSCs) indeveloping countries, such as Colombia, is an increasing problem. The PFSCs in developingcountries are characterized by high uncertainty and a dynamic environment. Furthermore, thehighest amount of food loss in these countries occurs in the early stages of the supply chainsuch as post-harvest and transport stages. Moreover, food loss in PFSCs in developingcountries has not been given sufficient amount of attention previously and needs to be givenattention in research, for these countries to be able to mitigate the problem with food loss. Research problem: To mitigate food loss in developing countries, knowledge is required ofwhy this occurs and how to solve it. This is why this research will focus on finding out themain different factors that lead to food loss in Colombian PFSCs and what solutions there areto mitigate food loss. Research purpose: The purpose of this thesis is to analyze PFSCs and the factors leading tofood loss, specifically the management of vital stages of PFSCs to target inefficiencies andreduce food loss in the context of Colombia. Research questions: RQ1: What factors can impact food loss in perishable food supply chains? RQ2: What factors in the vital stages of the perishable food supply chains in the Colombianmarket can help mitigate food loss? Conclusion: Our findings show different factors that were found to be contributing to foodloss in the PFSCs in Colombia. These were the lack of resources such as monetary,technology and knowledge, logistics factors such as cold storage, handling, infrastructure andtransportation and lastly, poor collaboration and communication. Furthermore, solutions tomitigate food loss were also found, these were technology (forecasting, cold chaintechnology), governmental policies and support, education, sufficient selling price, andfinally improved collaboration and communication. This shows that the factors leading tofood loss were many times the factors that would be solutions to food loss if improved. Ourmain conclusion was that food loss can be mitigated by collaboration and communicationwhich can be facilitated by technology.

This dissertation aims to provide models which will help companies make sustainable logistics management and transportation decisions. These models are extensions of the economic lot sizing model with the availability of multiple replenishment modes. The objective of the models is to minimize total replenishment costs and emissions. The study provides applications of these models on contemporary supply chain problems. Initially, the impact of carbon regulatory mechanisms on the replenishment decisions are analyzed for a biomass supply chain under fixed charge replenishment costs. Then, models are extended to consider multiple-setups replenishment costs for age dependent perishable products. For a cost minimization objective, solution algorithms are proposed to solve cases where one, two or multiple replenishment modes are available. Finally, using a bi-objective model, tradeoffs in costs and emissions are analyzed in a perishable product supply chain.

Contemporary supply chain management (SCM) issues are multiplex and continually evolving catalysed by complexities and dynamism. The perishable food industry exemplifies this phenomenon, driven by globalisation, technological advancements and a highly competitive business environment. Inescapably, food supply chains are increasingly operating as supply chain networks (SCN). SCNs are typified by a higher level of interdependence and connectivity amongst firms, consequently evolving from dyad and triad relationships, which have dominated SCM research. These changes generate divergent risks and vulnerabilities that perturb perishable food supply chains in unconventional ways. Thus, the purpose of this empirical study is to investigate how firms within a perishable food supply chain network can build resilience and sustainability. The research focuses on advancing the management of fast-moving consumer goods (FMCG). Methodologically, an empirical qualitative study is undertaken within a food manufacturer (focal firm) and 18 independent firms operating across all tiers of its SCN. Applying a pragmatic philosophical positioning, the study draws concepts from key supply chain theories to investigate the phenomena. The investigation uses Nicolini’s Zooming in and Zooming out as an analytical lens. The zooming in and out is established by shifting analytical lenses and re-positioning actors’ praxis, to ensure certain facets of their actions are fore-grounded while others are put in a background position and contrariwise moving the background to the foreground. The purpose of this technique is to draw meaning from everyday practices and trace the actions of actors across the entire SCN. The results uncover four distinct but intertwined main categories; whose subtle and often ignored interplay is crucial in attaining SCN resilience and sustainability. These main categories are Collaboration, Power Dynamics, SCN Culture and Information Systems. Current supply chain literature argues that collaboration is an essential enabler of resilience and sustainability. Building on this, the findings make a significant contribution by teasing out the intangible and predominately unacknowledged antecedents and salient sustaining factors of effective SCN collaboration. Furthermore, the study develops a resilience and sustainability (RS) matrix, which renders different impacts and outcomes of varying levels of SCN collaboration between firms operating in a perishable food SCN. Therefore, this thesis contributes knowledge towards constructing resilient and sustainable perishable food SCNs by proffering pragmatic propositions. These aim to address challenges facing industry stakeholders and ignite pertinent future research avenues for scholars.

The main aim of this thesis was to provide a comprehensive overview of the international transport of commodities with regard to its nature, time and cost efficiency. As a commodity suitable for examination were selected cut flowers. Based on the analysis of modes of transport was partial objective to propose directions for transport of cut flowers in the air and road transport with regard to the nature of commodities, time and cost efficiency. Another objective was to map the centers of production and consumption of cut flowers. Under this objective has been paid great attention to the center of international trade in cut flowers Netherlands and trading on local exchanges.

At the retail level, 25% of sellable food is wasted, and perishable foods account for 72% of food waste in the United States. The purpose of this qualitative phenomenological study was to explore the food waste reduction strategies used by supermarket perishable food department managers, which are covered under the Good Samaritan Food Donation Acts (state and federal). The participant population was comprised of 17 managers who are responsible for perishable foods departments (bakery, deli, meat, dairy, and produce) at local, regional, and national supermarkets in Midland, Michigan. Goal systems theory served as the conceptual framework lens for which the findings of this study are viewed. Data collected centered around long interviews and publicly available company documents. Interviews and field notes, including member checking, were transcribed and analyzed using NVivo software. Using methodological triangulation of these data sources, 3 themes emerged from the data analysis: the knowledge level of participants relative to the Good Samaritan Food Donation Act, factors that influence food waste and management strategy, and existing food waste reduction strategies. Most front-line managers are not aware of the Good Samaritan Food Donation Act. Factors that influence food waste include sell-by dates, personal bias, and food handling regulations. Existing food waste reduction strategies include donations, price reductions, stock rotation, and in-store repurposing. Positive social change may result from the results of this study if food waste can be further reduced or more food redirected to the needy. The study findings may be useful to supermarket managers as they consider the protection at the state and federal levels that the Good Samaritan Food Donation Act offers.

[pt] Esta dissertação analisa o problema da gestão de estoque de sanduíches de uma empresa prestadora de serviços de alimentação, a Tok Take Alimentação Ltda. Para tanto, foi feito um levantamento bibliográfico na área de gestão de estoques e de previsão de demanda. Para o estudo de caso, dados históricos do consumo diário de sanduíches em um determinado cliente foram coletados e submetidos à análise por meio de dois métodos de previsão de demanda: o método de médias móveis dupla e o método de amortecimento direto para dados sazonais. Desta forma, foram determinados dois modelos que possibilitam a previsão de demanda diária deste produto. / [en] This report analyzes the issue of managing the inventory of sandwiches of a food vending enterprise, Tok Take Alimentação Ltda. For that purpose, a bibliographic survey was made on inventory management and demand forecasting. In the case studied it was found that no gain could be obtained by expanding the replenishment period. Hence the analysis turned its focus to demand forcasting. For the case study, historical data of sandwich consumption at a specific client site were colected and submited to analysis by means of two forecasting methods namely: double moving average and direct smoothing for seasonal data. After that, a model that enables daily forecasting of that product`s demand was determined.

La presente tesis tiene como propósito principal elaborar un análisis y evaluación de los factores más importantes que determinan el desarrollo del servicio de transporte de productos alimenticios perecederos en un operador logístico en la cadena de frío, en función a las necesidades del cliente y al correcto funcionamiento del servicio; con la finalidad de que la empresa se consolide como operador logístico, brindando los servicios de almacenamiento, consolidación de mercadería, transporte y distribución. A partir de una entrevista con el gerente general y el coordinador de transporte se pudo comprender el origen de diversos problemas que vienen afectando al servicio de transporte, siendo este la falta de un análisis de factores que intervienen en la operatividad del servicio. Antes del análisis de dichos factores, se realizó una revisión bibliográfica de los antecedentes y las bases teóricas referentes al tema. A partir de ello se concluyó que existen muy pocos antecedentes en el Perú de estudios referentes al servicio de transporte de productos alimenticios perecederos y de la cadena de frío. Sin embargo, se encontraron estudios referentes a la cadena de frío en países como Venezuela, Colombia, Estados Unidos y otros países, lo cual nos dio a entender que la gestión de la cadena frío se encuentra más desarrollada en el extranjero. En base a esto, se elaboraron propuestas de mejora con las bases teóricas revisadas, registros de información brindados por la empresa e información adicional recopilada de los clientes. This thesis has as a main purpose preparing an analysis and evaluation of the most important factors determining the development of the service of transporting perishable foodstuffs into a logistics operator in a cold chain, according to the needs of the client and the proper functioning of the operations of the system; the company will obtain a strong base in the branch of the logistics department, providing storage services, consolidation of goods, transport and distribution. From an interview with the general manager and the transportation coordinator, it can be understood that the lack of an analysis in the logistics department is the origin of the diverse problems that are affecting the transport service. Before the analysis of these factors, a literature review of the history and theoretical basis concerning the issue was made. From this it was concluded, that there are very few precedents in Peru, relating to the studies of the transportation of perishable food products and cold chain. However, studies on the operational refrigeration in countries such as Venezuela, Colombia, United States and other countries, gave us information to understand that the management of the cold chain is more developed abroad. Based on the studies made proposals to improve the theoretical foundations were revised, and records of information were provided to develop the logistics process in Peru.

Supply chain managers in the retail grocery industry face significant challenges in reducing the wastage of perishable food. Perishable food spoilage and deterioration in the retail grocery industry result in a significant loss of profitability and consumer satisfaction. The purpose of this multiple case study was to explore the strategies that supply chain managers in the retail grocery business used to minimize perishable food loss. The perishable inventory theory was used as the conceptual framework. Data were collected from semistructured interviews with 6 Pennsylvania retail grocery supply chain managers who implemented strategies to minimize perishable food loss and from organizational documents. Data analysis was carried out using Yin's 5-step process of compiling, disassembling, reassembling, interpreting, and concluding data. The 3 emergent themes resulting from data analysis were inventory strategy, logistics and deliveries strategy, and information technology strategy. Member checking occurred after transcription and summarization of the interview data. The findings indicated that supply chain managers use first-in-first-out approaches to inventory management, rotation, replenishment, information sharing, and on-time purchasing to minimize perishable food loss. The findings and recommendations of this study might be valuable to supply chain management and retail grocery leaders to create strategic solutions to mitigate the loss of perishable food. The findings of this study might contribute to positive social change through the reduction of perishable food loss, an increased supply of food, lower retail prices to the consumer, and improved customer satisfaction.

Because of this, literature has been showing a renewed interest on the use of advanced planning tools in supply chain management of fresh food supplies. For the existing planning techniques covering fresh products supply chain have a very complex compounded by the perishable nature of these products. These peculiarities of the food industry require an intelligent and agile chain to manage customer needs. Therefore, supply chain management strategies emerge in literature providing a framework that identifies three types of strategies: lean, agile and leagile. Thus, the aim of this research is to develop a model for a strategic decision-making for the management of perishable products supply chain in the poultry industry, from competitive priorities and a selection of customers’ expectation factors for products. The research presents factors that can influence the strategic choice as competitive priorities, quality, cost, flexibility and time. These factors can guide companies in implementing efforts for the adoption of lean, agile or leagile strategies. In addition, this research presents the main aspects of retailers and restaurants demanded quality in relation to the manufacturer to meet the expectations of the end customer. Such results are presented individually and can be considered in the strategic choice when the focus is in attending retail, restaurants or both. Thus, the strategic decision of companies can be made with a focus on meeting the demands of their customers.
