Parametric Estimation and Constraint Programming-Based Planning and Simulation of Production Cost of a New Product

Abstract

Currently-used decision support solutions allow decision makers to estimate the cost of developing a new product, its production, and promotion, and compare the estimated cost to the target cost. However, these solutions are inadequate for supporting simulations of identifying conditions, by which the specific cost is reached. The proposed approach provides a framework for searching for possible variants towards reaching the target production cost. This paper is concerned with a prototyping problem of product development described in terms of a constraint satisfaction problem. The proposed method uses parametric estimation to identify relationships between variables, and constraint programming to search for project completion variants within the company’s resources and project requirements. The results of an experiment indicate that constraint programming provides effective search strategies for finding admissible solutions. Consequently, the proposed approach allows decision makers to obtain alternative scenarios within the limits imposed by the production process. In this, it outperforms current methods dedicated to the support of evaluating the total cost of a new product. The declarative approach presented in this paper is used to model the production cost; however, it can be effortlessly extended to other aspects of product development (e.g., product reliability).

Design and manufacture of four wheel tractor for medium size work rice farming

“…The development is very rapid, as the land in the United States (US) is huge and the immigrant increasing tremendously so that the source of food increase very rapidly too. In the US farmer history alone tractor has been operated under a series of fabrication starting from 1908 a tractor called Hart [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30]1924 IHC farm all, 1924 Allis Chalmers U., and 1939 the famous Ford 9 N. Ford Motor Co.'s tractor arm had already pushed the industry with its model F and its unprecedentedly low price in the 1920s. In 1939 they returned with the novel "threepoint hitch", as well as adopted the major industry advancements from the previous two decades.…”

“…The basic thinking of time reduction will be to equip each sub-assembly station with more automated tools, several assemblers, and a handling system so that the station should be able to complete its task within the given takt time [14]- [16]. Figure 6 illustrates the sub-assembly station along with respective operators in each assembly station subject to improvement every year until it could finish each task in only 8 hours in the fifth year of operation [17]- [20].…”

Reducing the Total Product Cost at the Product Design Stage

“…In the aspect of NPD, the CSP paradigm has been mainly used in the field of product design [8,9]. The use of CSP paradigm to cost estimation has been presented within the NPD cost, advertising cost, and unit production cost in [10]. This study develops previous research in the context of using the CSP paradigm to finding the trade-off between the cost of product development and the costs related to production and after-sales service.…”

“…Current methods of planning an NPD project use a procedural approach, in which an NPD model is built for a specific problem, and the process of designing the model ends when the structure of the model is sufficient to solve the problem. By contrast, in a declarative approach a single NPD model is developed, and it can be used to formulate various NPD-related decision problems [10]. A declarative representation of an NPD model provides a framework for applying effective techniques towards reducing the search space of possible solutions.…”

Identification of the Impact of the Availability Factor on the Efficiency of Production Processes Using the Ahp and Fuzzy Ahp Methods

“…Current market requirements result in an increase in demand for personalized products with unique features and functionalities tailored to specific customer needs (Zubrzycki et al, 2021;Relich & Świć, 2020). Providing a wide range of products is a huge challenge for manufacturing companies, which determines the nature of the organization's activities and functioning, and above all, the type and structure of the manufacturing system (Gola, 2014).…”
