Wijaya Karya Beton merupakan salah satu perusahaan yang bergerak dalam industri pembuatan tiang beton yang berlokasi di jalan Medan – Binjai Km 15,5 Desa Sei Semayang Kecamatan Sunggal, Kabupaten Deli Serdang. Perusahaan ini berproduksi bersadasarkan pesanan (make to order). Dimana permintaan yang tinggi akan menjadi keuntungan bagi perusahaan tetapi akan menjadi kerugian bagi perusahaan apabila tidak dapat memenuhi pesanan tepat waktu. Berdasarkan data masa lalu PT. Wijaya Karya Beton mengalami permintaan yang berfluktuatif dari bulan Januari- Desember 2019 namun tidak mempertimbangkan sumberdaya kapasitas produksi yang tersedia sehingga terjadi keterlambatan dalam menyelesaikan produk. Penelitian ini bertujuan untuk mengetahui kebutuhan kapasitas produksi dengan metode rough cut capacity planning serta menggunakan perhitungan peramalan sebagai acuan permintaan konsumen dimasa yang akan datang. Berdasarkan hasil laporan RCCP kekurangan kapasitas terjadi pada work centre III, V, VI, VII. Pada work centre III kekurangan kapasitas sebesar 114 jam dan pada work centre V kekurangan kapasitas sebesar 116 jam, langkah yang dilakukan untuk mengatasi kekurangan kapasitas dengan melakukan penyesuaian (readjustment) kapasitas dengan memindahkan beban kerja ke periode yang mengalami kelebihan kapasitas. Pada work centre VI kekurangan kapasitas sebesar 29140 jam dan pada work centre VII kekurangan kapasitas sebesar 2435 jam, langkah yang dilakukan untuk mengatasi kekurangan kapasitas dengan menambahkan jam kerja lembur disetiap bulannya. Setelah dilakukan penyesuain (readjustment) dan penambahan jam kerja lembur maka kapasitas untuk setiap work centre dapat terpenuhi.","PeriodicalId":37850,"journal":{"name":"Journal of Industrial Engineering International","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74806605","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Stasiun boiler merupakan salah satu stasiun yang ada di PT Perkebunan Nusantara III PKS Sisumut. Ketel uap (boiler) digunakan sebagai sumber tenaga dan sumber uap yang akan dipakai untuk mengolah kelapa sawit.. Stasiun boiler mempunyai suhu ruangan sebesar 29-420C akibat dipengaruhi oleh paparan panas dari tungku pembakaran boiler. Operator bekerja selama 8 jam kerja per hari dan berada di lingkungan kerja yang panas. Melalui pengukuran beban kerja, maka akan diketahui apakah kerja beban kerja seorang operator sudah optimal dengan adanya pengaruh temperatur disekitar lingkungan. Beban kerja yang diperoleh dari perhitungan komsumsi energi didapat hasil nilai rata-rata E = 8,031 Kkal/menit dan nilai rata-rata %CVL = 60,39 (kerja dalam waktu singkat) dikategorikan bahwa beban kerja operator merupakan beban kerja berat yang berarti operator tidak diperbolehkan beraktivitas dalam waktu yang lama. Dan temperatur yang diperoleh dari perhitungan rata-rata nilai ISBB pada stasiun boiler adalah 33,50C. Hal ini menunjukkan bahwa iklim kerja di stasiun boiler melebihi NAB. Dengan demikian, temperatur pada lingkungan kerja merupakan salah satu penyebab terjadinya kelelahan operator boiler saat bekerja. Berdasarkan persamaan regresi antara denyut nadi kerja dan temperatur diperoleh nilai korelasi 1,000. Hal ini menunjukkan bahwa denyut nadi kerja mempunyai hubungan antara denyut nadi kerja dengan temperatur. Semakin tinggi temperatur maka denyut nadi juga akan semakin cepat.","PeriodicalId":37850,"journal":{"name":"Journal of Industrial Engineering International","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87075302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most of the studies in this field concern processes whose response variables follow the normal distribution function, but in many industries and services, this assumption is not true. The presence of outliers in the historical data set could have a deleterious effect on phase I parameter estimation. Therefore, in this paper, we propose a robust cluster-based method for estimating the parameters of generalized linear profiles in phase I. In this method, the effect of data contamination on estimating the generalized linear model parameters is reduced and as a result, the performance of T^2 control charts is improved. The performance of this method has been evaluated for two specific modes of generalized linear profiles, including logistic and Poisson profiles, based on a step shift. The simulation results indicate the superiority of this cluster-based method in comparison to the non-clustering method and provide a more accurate estimation of the parameters.","PeriodicalId":37850,"journal":{"name":"Journal of Industrial Engineering International","volume":"18 1","pages":"88-97"},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88838367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, in this research, the selection of appropriate suppliers with respect to the multi-resource supply policy, and the implementation of lateral transshipment have been studied, and meta-heuristic algorithms have been employed to solve the problem. In the proposed method, the supply chain network is improved by minimizing the inventory shortages through utilizing lateral transshipment between different factories. In order to efficiently solve the problem, a hybrid meta-heuristic algorithm based on population-based genetic algorithm (GA) and single-solution simulated annealing (SA), named GASA, is propose, in order to simultaneously gain with the advantages of both algorithms, i.e., global search ability of GA and local search ability of SA. In order to compare the results of the proposed GASA, it is compared with GA and SA, to find the best solution. Given the parameters optimization and conducted analyses and comparisons of primary and hybrid algorithms performance, the hybrid GASA algorithm has been identified as the most efficient algorithm to solve the problem,compared to the other algorithms, emphasizing cost reduction and shortage volume.","PeriodicalId":37850,"journal":{"name":"Journal of Industrial Engineering International","volume":"58 1","pages":"52-62"},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84784451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Process incapability indices are created by transformation in the process capability indices, leading to the separation of information related to the process accuracy and precision. This separation of information can be very beneficial to specify whether the process is capable or not and to detect deviations in the production processes that produce high-tech products, such as the electronics industry. The main goal of this study is to propose a process incapability index by considering the measurement error for processes with multivariate quality characteristics. The efficiency of this index is then examined by a numerical example using Monte Carlo simulation method. Moreover, the performance of proposed approach is compared with the case where there is no measurement error. In addition, as a practical example, this index is compared with a number of recently proposed indices in the literature, and sensitivity analysis is conducted, as well. The simulation results showed that the measurement error has a significant effect on process capability and incapability indices. Therefore, we strongly suggest that the measurement error has to be considered in the process analysis.","PeriodicalId":37850,"journal":{"name":"Journal of Industrial Engineering International","volume":"15 1","pages":"14-31"},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73164201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since there are rare studies regarding how energy drives secure access to sustainability, this study explores the role of solar energy generation in economic, social, and environmental sustainability and energy security in Iran as the main purpose. Using a system dynamics computer simulation model, this paper defines factors affecting the system including four sub-models such as energy and three aspects of sustainability. Besides, energy security is defined as the availability of adequate energy supply to satisfy existing demand. After determining a causal loop diagram, dynamic models, specific trends, and validation and simulation of the system, separate policies are presented along with a combined policy for system improvement. The policies include enhancing foreign investment, increasing tariffs of non-renewable energies, and decreasing energy intensity. This study further reviews relevant policies set forth in the USA, Germany, and China. According to the results, improvement policies are coming to an end.

Through the result of diagnostic, for improving the performances of separator, the components E, R and F should given more attention and the results of prediction evaluation show that in comparing with perfect repair strategy, the imperfect repair strategy cannot degrade the performances of separator, whereas the CBM strategy can improve the performances considerably. These results show the utility of this approach and its use in the context of a predictive evaluation process, which allows to offer the opportunity to evaluate the impact of the decisions made on the future performances measurement.

The presented model is applied in a two-stage structure. The first-stage decisions confirm the establishment of distribution centers, whereas the second-stage decisions determine the other variables of the problem. For a better management of inventory, it has been used under the names of fresher first and older first policies. In the fresher first policy, the fresher items have a priority to be sent to the customer, whereas in the older first policy, the items with a longer age have the priority to be sent to the customer. The summary of the results of the models demonstrates that among the free, fresher first, and older first policies, it is the free policy that offers a higher profit function to the customer than the other two policies since it is more flexible and general,and encompasses these two extremes. The free policy lets the model determine which items to sell at any given time period in order to maximize profit.Moreover, in the older first policy, since the older items reach the customers sooner than the other items, the number of the expired items is reduced. However, this policy brings the lowest revenue to the customer. In the fresher first policy, since the fresher items are sold first and then the older items are sold, the number of the expired items is increased along the customer horizon. Nevertheless, the customer obtains more revenue compared with the older first policy.","PeriodicalId":37850,"journal":{"name":"Journal of Industrial Engineering International","volume":"97 1","pages":"32-41"},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85650597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
