Programming the production obtained by processing the raw materials in several operations that are repeated at certain time intervals previously set forth for various products aims the serial production organised by manufacturing batches. The size of the manufacturing series implies determining the optimal level of the manufacturing series that takes into account the correlation of the number of products that will be manufactured with the unitary expenses, which are in turn based on total expenses established according to the expenses incurred by the immobilisations of means and those related to the time to prepare-complete the manufacturing batch. The optimal size of the series influences the level of the manufacturing batch next to the size of the preparation-completion time, operative time, and manufacturing conditions. Based on the two previously established sizes, the duration of the manufacturing cycle is calculated, separately emphasising the duration of processing and of interruptions. Once the manufacturing cycle duration is established, the possible calendar moves forward and the size of the half-finished stocks necessary for the smooth operation of the flow manufacturing line is established. Balancing the scheduled production is to be done on that manufacturing line and takes into account its correlation with the production capacity for every workplace and each machine-operation during the period of repeatability of manufacturing batches and of the transport batches.

Abstract It has been found that the area where one can look for significant reserves in the procurement logistics is a rational management of the stock of raw materials. Currently, the main purpose of projects which increase the efficiency of inventory management is to rationalise all the activities in this area, taking into account and minimising at the same time the total inventory costs. The paper presents a method for optimising the inventory level of raw materials under a foundry plant conditions using two different control models. The first model is based on the estimate of an optimal level of the minimum emergency stock of raw materials, giving information about the need for an order to be placed immediately and about the optimal size of consignments ordered after the minimum emergency level has occurred. The second model is based on the estimate of a maximum inventory level of raw materials and an optimal order cycle. Optimisation of the presented models has been based on the previously done selection and use of rational methods for forecasting the time series of the delivery of a chosen auxiliary material (ceramic filters) to a casting plant, including forecasting a mean size of the delivered batch of products and its standard deviation.

Production Processes

The production processes are analysed, where multiple products are made in continuous or discontinuous flow, and their movement between two successive workplaces are performed in batches. It is a matter of homogenous groups of products and analogous groups of products that have the same order in terms of passing by the various workplaces, but it is not mandatory for these products to go by all workplaces. The processing times by operations of various products are not the same. Taking into account the synchronisation level, the flow production lines of the benchmarks can be in continuous flow or discontinuous flow, which requires or does not require an adjustment of the flow production line. It is necessary to know the order of assembling and delivering the finished products and the labour volume related to adjusting the machines to achieve a high level of loading the machines and equipment on the flow manufacturing line. The sizes, gauge, and volume of the parts that are processed on the flow production line must be known. It is necessary to elaborate the production schedule of the variable flow line that will take into account the nature of the products that are to be manufactured, the time needed to process each product at a workplace, the total product processing time achieved on that flow manufacturing line. For this, the level of loading every workplace and flow manufacturing line, the demand of performers stated in man/hour, time to occupy a job, and the manufacturing line, etc. will all be calculated. Should the production be achieved by production processes where a single operation is performed for similar products, but of different sizes or quality, the production schedule for this type of production shall correlate the production thusly achieved with the production capacity for a complete production cycle. Determining the frequency of releases of products into manufacturing is based on the criterion of production expenses totaled for all products that are made by processing in that operation.

Extractive industries (mining and quarrying, in particular) is a strategically important part of the primary sector of Ukraine. The current state of the extractive industries is characterized by a certain revival, however only in a few sectors. The purpose of this paper is to provide insights to the extractive industry performance and identify the main factors of change that will ensure growth in the primary sector. The analysis showed that as of today the extractive industry companies demonstrate low performance efficiency (a slowdown in production growth rate, fluctuations in cost effectiveness and profits, a significant share of unprofitable businesses), their technical and production capacity fail to meet the global trends which is underpinned by ineffective opportunity management in the given sector. For extractive industries, change management gains critical importance subject to their high environmental dynamism. Changes in the business environment in the mining and quarrying sectors are generated by the factors of space, time, consumer, safety, products, price – all of which initiate external changes; reduce (curtail) lag changes; trigger changes in the market infrastructure and the range of related services; promote government support extension; yet again prove the need for changes in extraction engineering and technology, raw materials processing and enrichment; assign changes in approaches to cost control and pricing methods. The key messages that make companies move forward to change should be: increasing difficulties in confronting the entropic effects of the external environment; crisis phenomena within companies; deterioration of market environment; company management or any stakeholders’ (their groups) initiatives of changes; contact group information on certain requirements for products, prices, resources cost, etc. The research findings have revealed the following headwinds that hamper changes: the lack of effective management and professional managers capable of implementing the entire cycle of changes; inefficient organizational structure, the presence of conflicts in the organization; resistance to change; undeveloped corporate culture of the enterprise.

Micro, Small and Medium Enterprises (UMKM) has an important role in the Indonesian economy, one of which can help the per capita income of the Indonesian state, especially in Banyuwangi Regency, as well as in the UM Banana Sale UD UD. Sumber Alam Buana, located at the eastern end of the island of Java, precisely in Banyuwangi. The UMKM is one of Banyuwangi's original typical food businesses from Ambon banana raw material, bearing in mind that typical food is identical to souvenirs (souvenirs) when visiting Banyuwangi, certainly not forgetting to bring and share them with you. However, there are problems in the field of production of UD Banana Banana UD, namely the low production capacity of processing banana raw materials because it still uses a cutting knife and the appropriate method has not been applied to record raw materials or finished goods so that the owner is less able to control the cycle of raw materials or finished goods. While in the marketing sector it is still conventional to be entrusted in a gift shop so that it can only wait for whether the product is sold or vice versa. The solution to the development activities of UMKM Sale Banana UD Sumber Alam Buana includes counseling and training using a banana chopper tool that is more efficient than a knife that has been used to chop banana raw materials. Whereas in terms of recording to help partners to control raw material inventory and finished goods efficiently and effectively, the need for training knowledge and assistance to owners and employees using a perpetual method stock card (inventory). To expand market share that has demanded the use of technology, training is held to make e-mail as a portal to access several e-commerce websites and to open online stores through social media such as Facebook and others. The results achieved in the Community Service program are the development of this business in terms of increasing production capacity, managing raw materials, expanding markets and increasing income.

Damage to the tendon-ligamentous apparatus places serious limitations on a personʼs physical activity. Injuries are especially common in physically healthy people leading an active lifestyle, such as athletes. To treat such injuries in orthopaedics and traumatology, autoplastic operations are performed or prostheses made of synthetic or biological materials are installed. The known treatment methods, in spite of their effectiveness, have a number of serious drawbacks, which often limit their use. Therefore, the search for new approaches and materials for plastic ligaments is an urgent task. Today, biotissue prostheses are accumulating advantages over their synthetic counterparts. The most promising raw material for biological ligament prostheses, due to its availability in the required quantity and optimal size, is the flexor and extensor calf tendons. This paper aimed to develop a method for treating xenogenic tendon to manufacture ligament prostheses and assessing its biocompatibility in a heterotopic implantation model. To manufacture a ligament prosthesis, the raw material was subjected to mechanical cleaning and chemical-physical treatment, as well as treatment with supercritical carbon dioxide fluid with the addition of the nonionic surfactant Tween 80, which together contributed to effective decellularization and removal of other biologically active components, while maintaining the physical and mechanical parameters and natural fiberarchitectonics of native raw materials. The biocompatible properties of ligament prosthesis specimens made from the flexor and extensor calf tendons using this method were evaluated in a model of heterotopic implantation into the subcutaneous adipose tissue of rats. The results obtained confirm the promising use of this material, treated according to the proposed method, in clinical practice.

The use of renewable energy and recycling products is one of the main achievements of organizations. The circular economy (CE) is a new concept which evolves out of a new management assumption in organizations based on recycling, reuse, and repurposing of products. The circular economy provides a framework for facing challenges and a guide for rethinking and redesigning the future. This chapter analyzes the Portuguese market for circular economy organizations based on discussion of the CE conceptual model. The circular economy is expected to contribute positively by introducing new methodologies for the production of raw materials, with new production processes and giving value to eco products. The challenge for Portuguese organizations is to create management “vectors” which promote networking innovation, labor, capital, and eco products. Overall, the conceptual model presented gives importance to Portuguese business decision making for sustainable consumption, which provides advancements in business for the green supply chain.
