Physicochemical and biochemical changes may occur in products of animal origin under the influence of internal and external factors, depending on the storage conditions. For the products made from the meat raw materials of various origins, it is important to know the optimal duration and modes of storage, which will preserve the optimal indicators of product quality and safety. The study aimed to determine the effect of different temperature regimes during storage on the quality and safety indicators of canned quail meat. Three series of experiments were conducted on the canned quail meat. In the first experiment, the quality indicators of the freshly prepared product were evaluated. In the second and third experiments, the parameters of the product were determined after aging for one year at temperatures of 2-4°С and 18-20°С. Organoleptic properties and physico-chemical and microbiological parameters were evaluated in the canned goods. The following methods of research were used: during the organoleptic assessment, it was considered the following properties: appearance, color, cross-section, smell, taste; fat content – by the Soxhlet method; hydrogen index (pH) – by the potentiometric method; microbiological indicators – by the horizontal method of counting colonies of microorganisms. It was found that the storage temperature did not affect the bacteriological indicators of the samples, which indicates the high quality of sterilization and excludes biological influence on the quality of canned goods. It has been established that, regardless of the storage temperature, the organoleptic indicators of canned food 12 months after production meet the state standard and the manufacturer's requirements, and they do not differ significantly. After one year of storage, the physico-chemical indicators of canned quail meat are within the limits of indicators established by the standard, regardless of the storage temperature. At the same time, certain changes were detected in the canned goods, which depended on the temperature conditions of storage. Considering the trends in physico-chemical parameters, the desired storage temperature for canned quail meat is 2-4 °C, although the increase in temperature to 18-20 °C does not lead to significant changes and it is permissible. Research is scientifically based on establishing the safety and quality of canned minced quail meat during long-term storage conditions, to create and produce high-quality and safe food products, which in turn allows for expanding the assortment of canned meat raw materials.

The present paper is part of a broader study of the authors, consisting of modeling and simulating several production systems. Functional modeling of a workstation supplied by various methods was carried out and presented in the paper [. This paper presents the functional modeling of an assembly line composed of 4 workstations with manual activities, designed to make 4 types of products (multi-product line). The supply with parts of the line is made with kitting system. The novelty of this study is the use of IDEF0 functional modeling method to describe the functioning of the assembly line in which the supply method is synchronous. The functional model developed had allowed to identify and to design the kitting and picking circuits, as for the highlighting of the traces followed by the components to the workstations, depending on their type of supply. This model can be extended and used to other assembly lines supplied in synchronous.

The present paper is part of a larger study of the authors, which consists in the analysis of performances of several production systems. The researches presented in this paper analyze the influence of the method of production flow management, the method of launching in production and the size of demand from the client on several performance indicators of a multiproduct assembly line supplied on stock. The assembly line is multiproduct type (are assembled 2 types of products that resemble as configuration and technology) and it has 5 workstations with mainly manual activities, that are supplied with parts using a synchronous method. The performance indicators considered were: average work in process, cost per unit, systems reactivity to client demand and throughput, their values being obtained by simulating the functioning of the assembly line in different experimental conditions, determined by the variation of the above mentioned parameters, using ARENA software. The synthesis of the results and their interpretation allow the process managers to take adequate decisions depending on targeted objectives.

The present paper is a continuation of a larger study of the authors, which consists of an analysis on the performances of several production systems. In this paper it is analyzed the influences of the method of managing the flows, the method of production programing and the clients demand on performance indicators of a multiproduct assembly line supplied on stock. The assembly line is designed to produce two types of similar products and is made of 5 workstations with mainly manual activities, which are supplied with parts on a stock based method. The performance indicators chosen for analysis were: average work in process, cost per unit, systems reactivity to client demand and throughput. The values of these indicators were obtained by simulating the assembly lines functioning in different experimental conditions, determined of the variation of above mentioned variables, by using ARENA software. The obtained results were interpreted and structured, in a manner to help the process managers to take adequate decisions considering the wanted objectives.
