Advancement in machining technology of curved surfaces for various engineering applications is increasing. Various methodologies and computer tools have been developed by the manufacturers to improve efficiency of freeform surface machining. Selection of the right sets of cutter path strategies and appropriate cutting conditions is extremely important in ensuring high productivity rate, meeting the better quality level, and lower cutting forces. In this paper, cutting force as a new decision criterion for the best selection of tool paths on convex surfaces is presented. Therefore, this work aims at studying and analyzing different finishing strategies to assess their influence on surface texture, cutting forces, and machining time. Design and analysis of experiments are performed by means of Taguchi technique and analysis of variance. In addition, the significant parameters affecting the cutting force in each strategy are introduced. Machining strategies employed include raster, 3D-offset, radial, and spiral. The cutting parameters were feed rate, cutting speed, and step over. The experiments were carried out on low curvature convex surfaces of stainless steel 1.4903. The conclusion is that radial strategy provokes the best surface texture and the lowest cutting forces and spiral strategy signifies the worst surface texture and the highest cutting forces.

This chapter focuses on the selection of an audit firm by UK initial public offering (IPO) firms. It documents that many IPO firms switch to an audit firm in a different segment (big, midsize, or small), which suggests that IPO firms carefully select an audit firm of a particular quality level before they go public. It examines whether the selection of an auditor by IPO firms is driven by the demand for certification or insurance. The authors find that IPO firms are more likely to choose a high-quality auditor when the uncertainty of the firm’s future prospects is higher and they want to signal quality (certification driven by signaling). In addition, they find that firms with riskier IPO offerings select higher-quality auditors, in line with the insurance hypothesis. They find mixed results for the certification hypotheses when testing for the effect of auditor reputation on initial returns.

The article deals with the formation programs of individual tours. Based on the selection of specific features of individual tourist programs the authors define individual tourism stating that the main specific features of the individual tour is that the product is developed based on the desires and preferences of a particular tourist. It is shown that the individual tourist product allows meeting the needs of the tourist. Topicality is determined by the characteristics of the tourism market at the moment. The crisis that characterize Russian tourism today force to seek new approaches and new content in tourist activity in order to suggest possible ways to diversify the tourist offer, one of which is the individualization of tourist programs. The article also examines the specifics of individual programs, tours, given comparative characteristics according to different characteristics of mass and individual tourism products. Identified are the main advantages and disadvantages of acquisitions and trip planning of the individual program for tourists. The authors cover the basic steps and principles of formation and promotion of individual tourism products. Revealed is a difference in the sequence of the process of its development over the standard tour. Based on the study of offers of tourist companies categories of the most popular destinations of individual tourism are identified on the basis of which a classification of individual programs is proposed. On the basis of the study in the article suggested are the main characteristics of the different categories of consumers of individual tourism products. The article shows the prospects for the development of individual tourism products in the Russian tourist market. Based on the analysis of the actual supply of tourist services identified are the advantages and disadvantages of individual tours. The necessity of developing specific standards of service is explained. Due to the fact that the individual trip of tourists have special expectations, it is necessary to ensure the highest quality level of service in accordance with the program of travel. Characterized are the features of the technology of individual tourism, which aims to create a unique product.

Proposed Model

An acceptance sampling plan plays a very important role in any quality assurance system. In this new economical design of acceptance sampling plan, three types of costs are included in the objective function by considering average outgoing quality limit (AOQL), average quality level (AQL) and lot tolerance percent defective (LTPD) constraints based on the maxima nomination sampling (MNS) method in a two-stage approach. The design of this sampling inspection plan involves the minimum average total inspection (ATI). The model is designed to minimize the summation of costs and the proposed MNS economical sampling plan is compared with the classical one. Practitioners can use the proposed model to decrease the total cost of inspection.

AbstractThe subcontractor selection decision is inherently a multicriterion problem. It is a decision of strategic importance for companies. The nature of this decision is usually complex and unstructured. Management science techniques might be helpful tools for solving these kinds of decision-making problems. In this research, the fuzzy logic method and the analytic hierarchy process were applied for the selection of suitable subcontractors in an apparel supply chain.In general, many factors, such as quality level, price offer, and delivery delay, were considered to determine the most suitable and reliable subcontractors that fit the company's strategy. This survey is carried out using the database of an apparel company manufacturing denim products.

Abstract Finding the biggest cutter is expected to help in the selection of the right sets of tools and the right type of cutter trajectories, and thereby ensure high production rate and meet the required quality level. In this paper, we describe a new geometric algorithm to determine the biggest feasible cutter size for 2-D milling operations to be performed using a single cutter. Our algorithm works not only for the common closed pocket problem, but also for the general 2-D milling problems with open edges. In particular: • We give a general definition of the problem as the task of covering a target region without interfering with an obstruction region. This definition encompasses the task of milling a general 2-D profile that includes both open and closed edges. • We discuss three alternative definitions of what it means for a cutter to be feasible, and explain which of these definitions is most appropriate for the above problem. • We present a geometric algorithm for finding the maximal cutter for 2-D milling operations, and we give an outline of a proof that our algorithm is correct.
