Decision to maintain sales price at the same level/reduce, is taken at stages 2, · · · , k − 1, k. On the items attaining CLT, they are sold at scrap value, provided items are still left in stock. Customer arrival forms a non-homogenous Poisson process, with rate increasing with each sales price reduction. Service time follows exponential distribution.The items are replenished according to (S, s) policy with positive lead time. Each stage of CLT is iid which follows a Phase type distribution with representation(α, S) of orderm. The k-fold convolution of this distribution is the CLT of the inventoried items. The problem is modelled as a queueing-inventory problem which is a continuous time Markov chain (CTMC). The stationary distribution of this CTMC is computed and various performance measures are discussed. A cost function is constructed to compute the optimal order quantity and reorder level.The model is compared with queueing inventory model in which the CLT follows Erlang Distribution of order k.","PeriodicalId":365908,"journal":{"name":"3C Empresa.

Intelligent manufacturing is the process of enhancing production through the use of cutting-edge technologies, sensor integration, analytics, and the Internet of Things (IoT). The proposed paper mainly focuses on the study of the scope and the evolution of quality control techniques from conventional practices to intelligent approaches along with the state of art technologies in place. The challenges faced in building intelligent QC systems, in terms of security, system integration, Interoperability, and Humanrobot collaboration, are highlighted. Surface defect detection has evolved as a critical QC application in modern manufacturing setups to ensure high-quality products with high market demand. Further, the recent trends and issues involved in surface defect detection using intelligent QC techniques are discussed. The methodology of implementing surface defect detection on cement wall surfaces using the Haar Cascade Classifier is discussed.","PeriodicalId":365908,"journal":{"name":"3C Empresa.

Small and medium-sized enterprises (SMEs) typically have a simpler organisational structure than large corporations, which allows them to be more adaptable, provide instantaneous feedback, have shorter decision-making chains, and respond more quickly to customer needs. Even so, SMEs face enormous pressure to stay competitive in both domestic and international markets. Globalization, new technologies, and evolving consumer preferences are all contributing to a shift in the competitive landscape. These shifts are compelling small and mediumsized enterprises to adopt cutting-edge manufacturing techniques. The goal of this research is to identify the critical success factors (CSFs) that will help and guarantee that SMEs will be able to successfully implement AMTs (SMEs). Literature-based CSFs for AMT deployment are collected and fine-tuned using input from professionals in the field and scholars in the academy. The method of interpretive structural modelling (ISM) is applied to this CSF analysis. According to the ISM study, the three most important factors influencing the adoption of AMT are \"Top management support and commitment,\" \"entrepreneurial environment,\" and \"financial availability.\" The desired goal of AMT implementation is found to be \"performance improvement\" and \"sustainable AMT implementation.\" The identified CSFs and the structural relationship between them will help SMEs' top management create and prioritise business strategies that ease the implementation of AMT. The study's results point potential AMT financiers in the right direction by highlighting a handful of critical considerations that will improve the project's chances of success.","PeriodicalId":365908,"journal":{"name":"3C Empresa.

Model I is on a single-server queueing system in which the arrival process follows MAP with representation D = (D0,D1) of order m and service time follows phase-type distribution (β, S) of order n. When a customer enters into service, a generalized Erlang clock is started simultaneously. The clock has k stages. The pth stage parameter is θp for 1 ≤ p ≤ k. If a customer completes the service in between the realizations of stages k1 and k2 (1 < k1 < k2 < k) of the clock, it is a perfect one. On the other hand, if the service gets completed either before the kth1 stage realization or after the kth2 stage realization, it is discarded because of imperfection. We analyse this model using the matrix-geometric method. We obtain the expected service time and expected waiting time of a tagged customer. Additional performance measures are also computed. We construct a revenue function and numerically analyse it. In Model II, a single server queueing system in which all assumptions are the same as in Model I except the assumption on service time, is considered. Up to stage k1 service time follows phase-type distribution (α′ , T′) of order n1 and beyond stage k1, the service time follows phase type distribution (β′ , S′) of order n2. We compare the values of the revenue function of the two models","PeriodicalId":365908,"journal":{"name":"3C Empresa.
