Abstract

The design and optimisation of a logistic network deals with a wide set of decisions, e.g. the determination of the best location and capacity of the different logistic facilities (production plants, distribution centres, transit points, wholesalers, etc.), the allocation of the product demand coming from customers in presence (or absence) of fractionable flows of material, the determination of the best transportation mode (truck, rail, etc.) as well as loading and routing of vehicles. These decisions involve multiple stages of a distribution network: customers-regional distribution centres (RDC), RDCs-central distribution centres (CDC) and CDCs-production plants and sources, in presence of multiple products and the variable time (i.e. time-dependent product demand and flows of material). This paper presents a top-down methodology that joins the strategic planning, the tactical planning and the operational planning of distribution networks with a special focus on the development of effective heuristic methods to face the vehicle routing problem. Original models and heuristic algorithms for the operational planning are illustrated. The impact of the strategic and tactical decisions on the performance of the operational planning is evaluated by the application of the proposed hierarchical approach to two realistic case studies. Obtained results are illustrated in a what-if experimental analysis conducted on multiple problem settings and realistic scenarios.

– Modern supply chains collect and deliver products worldwide and link vendors and consumers over thousands of miles. In the food industry, the quality of products is affected by manufacturing/processing and logistics activities, such as transportation and packaging. Specifically, transportation is likely the most critical step throughout the “food journey” from farm to fork because of the potential stresses that affect the products during shipment and storage activities. The purpose of this paper is to present and apply an original assessment of quality, safety and environmental effects due to the international distribution of food products via different container solutions. A case study that examines the shipment of edible oils from Italy to Canada demonstrates that the quality of a product at the place of consumption can be significantly affected by the use of different containers.

Abstract

Food industry is the first in European Community for revenues, with more than 8 millions of employee. Logistics and supply chain management play a crucial role in food industry.

This paper presents a general and conceptual framework for the assessment of food supply chain (FSC) and logistics of food products in agreement with a multidisciplinary and integrated view. The target of the proposed integrated approach to supply chain design and management is the simultaneous control of quality (1), safety (2), sustainability (3) and logistics efficiency (4) of food products and processes along the whole FSC “from farm to fork”.

A case study focused on package design, distribution issues, and supported by the development of an original close-loop control system is a first exemplifying step towards a new integrated approach on FSC assessment in agreement with the proposed conceptual framework.

Finally, the paper presents a discussion on the most important challenges in FSC for public and private research in industry and in academic institutions.

Abstract

oliveThe effects on quality and safety of foodstuffs after transportation process are important for both the producers and the consumers. Herein, a shipment of different bottled vegetable oils (olive oil, extra virgin olive oil and grape seed oils) from Italy to Taiwan, has been simulated within a climate-controlled chamber. The treated samples have been chemically and sensory analyzed, considering basic quality parameters; then, the results were compared with the non-simulated oils from the same production batches. The analyses demonstrate that there is a risk of oxidation due to the shipment to be taken into account

Abstract

This paper presents an original top-down approach, made of original models and solving methods, and a decision support system (DSS) for the execution of the strategic planning, the tactical planning and the operational planning in a multi-echelon multi-stage multi-commodity and multi-period production, distribution and transportation system. The DSS is a software platform useful for the design, management and control of real instances. It can efficiently supports the decision making process of logistic managers and planners of large enterprises as multi-facilities companies and production–distribution networks. A significant case study is illustrated. The results obtained by the application of different problem settings are compared and discussed.

Abstract

Traceability is becoming a method of providing safer food supplies and of connecting producers and consumers. Recent diseases such as bovine spongiform encephalitis (BSE) and the questions concerning genetically modified organism (GMO) mean systems that enable control of each link in the food chain have become particularly relevant. Furthermore, although EU law no. 178 came into effect on the 1st January 2005, at the time of writing the regulatory situation is very confused.

The aim of this paper is to analyze legal and regulatory aspects of food traceability, and to provide a general framework for the identification of fundamental mainstays and functionalities in an effective traceability system.

Possible technical resources were clarified by analyzing assessment criteria obtained from studies of alphanumerical codes, bar codes, and radio frequency identification (RFID).

Finally, the paper presents the traceability system used by Parmigiano Reggiano (the famous Italian cheese) which was developed using the proposed general framework. Based on an integration of alphanumerical codes and RFID technology, the system is working well with very good results for both cheese producers and consumers.

Some interesting observations concerning development trends and traceability system costs close the paper.

Abstract
The aim of this paper is the analysis and examination of the industrial processes for Mozzarella pizza cheese (hereafter referred to as pizza cheese). Specific phases and mechanical devices are studied in order to optimise and rationalise the production cycle. This goal is reached by developing a new and innovative forming method. At present pizza cheese is produced in 1–5 kg pats whereas, as this paper intends to highlight, by forming the cheese in smaller-sized dimensions (5–10 g) the processes will benefit in terms of energy consumption and use of resources (equipment, water, time etc.). Another advantage would be that the customer would be provided with a ready-to-use product, without the need for additional cutting.

The paper deals with an innovative process for pizza cheese production, by focusing mainly on the forming phase; a double-screw extruder with a productivity of 20 kg/h was designed and tested in order to evaluate its functionality and applicability.

The most relevant spin-offs deriving from the new forming device are the elimination of the pre-hardening phase, the reduction of the chilling time of about 10-fold, the reduction of the total processing time of about 25% and the diminution of the refrigerant water consumption.
