The article shows that modern production systems must be able to perform various machining operations and quickly adapt to changes in consumer demand. When planning processes, only the capabilities of production resources are taken into account, but not their quantity, availability and condition. Plans created under these conditions can easily become ineffective or invalid. Changes to the original process plans or even redevelopment then become commonplace at the production floor level. This will significantly affect the productivity of production systems and industrial enterprises.

Abstract Applications of hybrid technology are expanding from refurbishment and repair to low quantity, specialty part production, which are staple characteristics in medical implant, energy, and aerospace industry sectors, among others. This expansion has led to the development of the Mazak VC-500A/5X AM HWD, a wire fed laser cladding unit equipped with a standard 5 axis CNC. This unit is capable of building near net geometry of complex medium to large parts within a profitable timeframe, due to its comparatively high rate of deposition to that of a powder fed hybrid system. In this study, deposition and machining capabilities of the VC-500A/5X AM HWD are assessed through the production of three different test geometries by different process plans. Production of these test geometries is supported by an open loop sensor package primarily for monitoring machine health, data collection, and machine operator aid. The viability of extended deposition followed by machining is evaluated against a more cyclical strategy of reoccurring deposition and machining operations. Lastly, common defects in as-built geometries are evaluated and addressed through revisions to original process plans and toolpaths, indicating the need for continued innovation in hybrid manufacturing specific CAM/CAD software, as well as closed loop machine monitoring and quality control.

Оптимальная производственная система обеспечивает выпуск конкурентоспособных бизнес-продуктов и расширенное воспроизводство. При этом с точки зрения системного подхода  решаются две задачи:– собрать в производственную систему необходимые и достаточные для производства конкурентоспособного продукта процессы;– гармонизировать между собой производственные, управляющие и обеспечивающие процессы в оптимальной производственной системе с целью максимизации ее синергии.А это во многом определяется уровнем интеллектуальной собственности предприятия.База интеллектуальной собственности структурирована по следующим направлениям (факторам): компетенции персонала, оцененные в соответствии с требованиями современного технологического уклада; реальные индивидуальные достижения персонала; портфель освоенных и перспективных технологий и конструкций в областях продукции и оснастки; технические решения в области конструкций и технологий (способов изготовления), защищенные патентами; ноу-хау в областях техники и технологий, организации и управления, не защищенные патентами; методики обеспечения синергии взаимодействия персонала; его удовлетворенности; корпоративной культуры; удовлетворенности и создания большей взаимовыгодной ценности заинтересованных сторон предприятия.Рассматривается модель управления интеллектуальной собственностью; формирование, оценка и актуализация индивидуализированной и общей баз интеллектуальной собственности предприятия; модель оптимальной производственной системы.Модель оптимальной производственной системы с учетом интеллектуальной собствен­ности предприятия позволяет объективно принимать решения для разработки плана органи­зационно-технических мероприятий по улучшениям процессов и производственной системы в целом.А по анализу эффективности бизнес-продукта в целом и отдельных процессов в частности предприятие может проводить повышение эффективности своей деятельности.При этом оцененная интеллектуальная собственность предприятия позволяет формировать команды, обеспечивающие решение инновационных проблем.

We propose a nonsmooth dynamic system integrating production and inventory where the items may deteriorate and the demand is stock-dependent. We aim to derive the optimal production rate. In our first model, backorders are not allowed, while in the second model they are. Using optimal control, necessary optimality conditions are obtained for general forms of the cost, demand, and deterioration rates and closed form solutions are derived for specific forms of these rates. Numerical simulations are presented and sensitivity of the solutions are examined.

This paper presents the concept of including the energy cost as a part of the total cost of manufacturing using machining processes in the development of computer aided process plans. The research objective is to index and evaluate the process plans based upon the energy consumption of the machining operations while considering machining cost and to rank or index the process plans based on energy consumption for purposes of decision support in process plan selection. The paper also discusses energy evaluation of process plans and their subsequent effectiveness in terms of overall cost associated with the utilization of effective machining parameters. The MPSEL system, which is an expert system based application, was used to develop alternative process plans. The MACH program, which is a spreadsheet based system, was used to determine the cost associated with machining. The developed process plans are compared based upon the cost associated with utilized energy and machining.

AbstractUS agriculture operates in a market driven economy, although government policies can have influence on what farmers produce and how they produce it. As with other businesses, agricultural producers respond to economic incentives and disincentives, and make decisions to maximize their welfare; usually measured as net income. We examined how external economic drivers shape the type of agricultural systems that producers adopt. Specifically, we considered the influence of technological advancements, income supports embodied in farm legislation, and changes in market structure and consumer demand. Changes in technology have often favored large-scale and specialized operations. Many of the technological advancements have required large-scale production units to justify the investment. Often the technology has been commodity specific. However, there is some evidence that more diversified production units might be able to achieve economies of both scale and scope. The influence of commodity support programs has been ambiguous. As farm legislation has evolved to decouple production decisions from program benefits, the incentives to specialize in program crops (crops that receive price and/or income benefits under federal legislation, such as corn, other grains and oil seeds) have diminished. However, wealth and risk effects, albeit small, may have promoted or inhibited the adoption of a more integrated system. The ability of producers to adopt more integrated systems has been primarily influenced by their natural resource base and proximity to markets. Changes in market structure, channels and consumer demand in the past five decades have been dramatic with consolidation and specialization in both production and marketing sectors. However, the diversity of consumer demand has also created opportunities for more integrated farm operations. There is an increasing number of consumers who have become concerned about how and where their food has been produced. Markets for organic, locally produced, free range and the like are expected to grow. While price and income supports may have been biased towards specialization (as these programs were targeted to specific commodities), the reduction in risk associated with the programs has enabled producers to expand the number and diversity of their production enterprises. Furthermore, through the use of strategic alliances, cooperation among producers on a regional basis may eventually lead to greater integration and diversification than could be achieved for the individual farm operation.

Organizational culture is the driving force behind the transformation of the enterprise. Effective improvement of production systems of industrial enterprises is based on the use of organizational culture resources. The development of the production system is an ongoing process based on such key elements as the management system, management processes and organizational culture. The quintessence of such development is the formation of the cultural shell of the enterprise and the establishment of ideal production, where people are the only active resource, since without them self-development is impossible. The stages of applied measures to improve the production system with various resources that include key development elements: the management system and processes, the formation of a system for collecting, analyzing and using best practices in order to increase the competitiveness of the enterprise, building a self-developing system of continuous improvements, creating an organizational culture that allows maximize the potential of employees and develop their abilities, have been considered in the article. Each stage of the development of PSP must pursue a goal of forming a loyal team.

Productivity is the most important indicator of labor efficiency. Productivity estimates poorly take into account the interaction of production systems equipment and the technological complexity of labor objects. There is proposed an integral assessment of the performance of these systems, which characterizes the effectiveness of the financial expenses of production resources in the manufacture of parts. It is proposed to characterize their technological complexity by multiplying the increase in the labor subject value after technological impact by the part release volume. The proposed assessment can be used in the development of software applications that automate the tasks of analyzing the effectiveness of production systems.

Tool condition monitoring (TCM) is an important aspect of condition based maintenance (CBM) in all manufacturing processes. Recent work on TCM has generated significant successes for a variety of cutting operations. In particular, lower cost and on-board sensors in conjunction with enhanced signal processing capabilities and improved networking has permitted significant enhancements to TCM capabilities. This paper presents an overview of TCM for drilling, turning, milling, and grinding. The focus of this paper is on the hardware and algorithms that have demonstrated success in TCM for these processes. While a variety of initial successes are reported, significantly more research is possible to extend the capabilities of TCM for the reported cutting processes as well as for many other manufacturing processes. Furthermore, no single unifying approach has been identified for TCM. Such an approach will enable the rapid expansion of TCM into other processes and a tighter integration of TCM into CBM for a wide variety of manufacturing processes and production systems.
