This paper focuses on a quantitative analysis for grasp planning and fixture design based on an analytical description of point contact restraint. In the framework, the analysis deals with the fundamental concepts of restraint cone, freedom cone, force-determinacy and relative form closure. A method is presented to quantify the performance of a fixture (or grasp) with two major characteristics of inner force distribution and load capacity. Two different fixturing (or grasp) models of simplex grasp and elastic grasp are presented. It is shown that the performance of these two types of grasp (or fixturing) could be measured with different performance indices. A minimax index (MMI) and a volume measure are defined for evaluating a simplex grasp, while a measure using the tolerable range of differential motion in the twist space or the allowable load polyhedron in the wrench space would be suitable for quantifying robustness and load capability of an elastic fixture system. Furthermore, for fixture system design a geometric analysis and reasoning procedure is described for the design of locators, clamps and supplementary supports. The aim of these proposed analysis and design techniques is to provide a scientific foundation for automated grasping/fixturing system design in the engineering practice.

Customer requirement analysis has become a primary concern for companies who compete in the global market. Kano’s model, as a customer-driven tool, has been widely used for customer requirement analysis in product improvement. Although a number of authors have improved the traditional Kano’s model, there has been a limitation of dealing with the fuzzy and uncertainty of human thought under multi-granularity linguistic environment. Furthermore, the traditional Kano’s model faces problems regarding quantitative data computation and customer requirements importance assessment. In this article, an improved fuzzy Kano’s model is proposed to analyze customer requirements under uncertain environment. A 2-tuple linguistic fuzzy Kano’s questionnaire is developed to model the uncertainty and diversity of customers’ assessments using 2-tuple linguistic variables under multi-granularity linguistic environment. Then, a comprehensive and systematic methodology is presented to prioritize customer requirements through quantitative analysis of improved fuzzy Kano’s model. This method integrates subjective judgments assigned by decision maker, objective weights based on maximizing deviation method and customer satisfaction contribution to determine the priority ratings of customer requirements. A case study of combine harvester development is presented to evaluate the proposed model.

The article provides a review and analysis of the current state of development of 4x4 ATVs and the scope of the developed ATV, a comparison of ATVs with mechanical and electromechanical transmissions, as well as their technical characteristics. The selection and justification of the design solutions for a 4x4 ATV with an electromechanical transmission are given on the basis of the following electric drive schemes considered in the article: “Electric motor instead of ICE”, “Motor axis”, “Electric motor-half axis”. The general design solutions of the ATV being developed is also presented based on the selected electric drive scheme.

The article is devoted to the results of an actual study, the purpose of which was to develop and implement design solutions for adaptively supporting configurations of the “1C: Enterprise 8.3” platform for subsequent practical application in the development of typical configurations for solving applied problems of small and medium-sized enterprises. The relevance of the study is determined by several positions. Firstly, the introduction of information technologies in the most important sectors of the economy helps to increase labor productivity, improve the overall investment climate in Russia, and helps to reduce the dependence of the country’s economy on commodity exports. Secondly, the low degree of realization of the potential of boxed solutions is due to the fact that many enterprises relate to the implementation and subsequent maintenance of such solutions as technical projects, not taking into account their business component. Thirdly, in some cases, when purchasing a replicated solution, it needs to be adapted to business requirements and the new IT infrastructure. Adaptation is carried out at the implementation stage or at the stage of supporting the implemented solution. However, the success of such work depends not only on the implementation and support specialists, but also on the availability of descriptions of specific rules, actions, and work that must be performed. At the same time, a lack of logically structured recommendations on their adaptation after acquisition and implementation is noticeable. The study took place in two stages. At the theoretical and methodological stage, a study of the subject area was carried out. The use of structural and object-oriented analysis and design tools made it possible to analyze the business processes of transferring data from the existing BOSS-Kadrovik automated system (AS) to 1C: ZUP, as well as the process of writing off material balances from account 10 to “1C: Accounting 3.0”, identify problem areas (analysis of IDEF0 functional models) and formulate the image and boundaries of the project (requirements model in the form of a use case diagram – Use Case). Selected adaptive support options were determined in accordance with the support rules recommended by 1C when implementing standard implementation technology. For the “1C: Salary and Enterprise Management 3.1” configuration, it was decided to develop a configuration extension, for adapting the “1C: Accounting 3.0” configuration, the creation of external processing. The design phase of work on the topic of this study involved the development of design solutions for the adaptation of the indicated configurations. At the same time, data models were developed at the logical and physical levels, the requirements for information support in the form of database directories were formulated. In addition, the dynamic component of the solutions being developed was examined, namely, the transitions of some objects from one state to another when fulfilling the selected precedents and the results of the state change. For these purposes, a special type of UML diagram technique was used – activity diagrams. Implementation of design solutions for adaptive configuration support was carried out on the 1C: Enterprise 8.3 platform. Testing the implemented solutions yielded positive results. In addition, the cost of adaptive support was calculated. In the calculation, the time norms for the configuration stage proposed by 1C were taken into account.
