“…However, during developmental projects, the majority of decisions are made during the early stages (Martin et al. , 2007; McAloone and Bey, 2009; Saravi et al. , 2013; Shehab and Abdalla, 2001; Zrim et al.…”

“…Table 1 shows that most of the clustering efforts presented in the literature focus on the end of the development phases. However, during developmental projects, the majority of decisions are made during the early stages (Martin et al, 2007;McAloone and Bey, 2009;Saravi et al, 2013;Shehab and Abdalla, 2001;Zrim et al, 2006). When a development decision is made, it is typically expensive to change it.…”

PurposeThe purpose of this paper is to investigate the impact of early-stage maintenance clustering. Few researchers have previously studied early-stage maintenance clustering. Experience from product and service development has shown that early stages are critical to the development process, as most decisions are made during these stages. Similarly, most maintenance decisions are made during the early stages of maintenance development. Developing maintenance for clustering is expected to increase the potential of clustering.Design/methodology/approachA literature study and three case studies using the same data set were performed. The case studies simulate three stages of maintenance development by clustering based on the changes available at each given stage.FindingsThe study indicates an increased impact of maintenance clustering when clustering already in the first maintenance development stage. By performing clustering during the identification phase, 4.6% of the planned work hours can be saved. When clustering is done in the planning phase, 2.7% of the planned work hours can be saved. When planning is done in the scheduling phase, 2.4% of the planned work hours can be saved. The major difference in potential from the identification to the scheduling phase came from avoiding duplicate, unnecessary and erroneous work.Originality/valueThe findings from this study indicate a need for more studies on early-stage maintenance clustering, as few others have studied this.

“…Matrix-based approach was widely used approach for functional synthesis, 31 which is always the lack of a uniform interface representation model, such as kinematic state pair-based functional model proposed in this article, to enable functional synthesis with a general interface representation model. At the same time, cost is an important factor in mechanism transmission, so how to integrate functional synthesis of mechanisms with cost is also an important issue.…”

“…29 As over 70% of the production cost of a product is determined during the conceptual design stage, reducing the cost of a product at the conceptual design stage is an effective way. 30,31 The above approaches could achieve combinatorial exhaustive solutions, in the absence of cost of mechanisms. However, how to produce optimal solutions of mechanisms with low cost is an important issue in the current product design.…”

Functional synthesis of mechanisms plays a crucial role in mechanical product design, which has an essential effect on the product innovation and cost. However, current functional synthesis algorithms of mechanisms are either inextensible to achieve complex mechanism solutions or prone to a loss of optimal solutions without consideration of cost. This article proposed a systematic kinematic state-based methodology for functional synthesis of mechanisms under cost consideration. After a general functional representation model based on the kinematic state pair is proposed with a result of the kinematic state space, an exhaustive functional synthesis of the kinematic state pair with the lowest cost algorithm is then proposed to produce solutions with K-lowest cost. The functional synthesis of a feeding mechanism device for cold heading machine is given as an example, which demonstrates that the methodology is obviously helpful to produce valuable functional chain solutions with low cost.

“…The experiments were carried out according to Taguchi’s orthogonal array (OA), as Taguchi’s method had been successfully used to optimize many manufacturing process parameters. 14–16 Besides shrinkage, the influence of chosen process parameters on tensile strength (TS) of the investment cast part has also been studied. Furthermore, confirmatory experiments have been conducted to validate the obtained optimal settings for LS, VS and TS of the IC part.…”

This study explores about enhancing the permeability of the ceramic shells used in the investment casting process using cheaply available sawdust particles. An increase in shell's permeability augments the cooling rate of the casting which enhances its mechanical properties. It was found that the inclusion of sawdust particles into the ceramic slurries exhibited positive impact on the shell's permeability. It is a well-known fact that electromagnetic stirring process increases the mechanical properties of the castings, but its effect on casting shrinkage has never been realized. Thus, this study further throws light on the impact of electromagnetic stirring in reducing the shrinkage and improving the tensile strength of the casting. In a nutshell, it was found that the final product quality of the investment cast part improved by the combinational treatments adopted in this research work.
