Through this procedure, we discover the pressure distributions, velocity vectors, and temperature gradients. This analysis demonstrates that the temperature values between the simulated and experimental values differ.","PeriodicalId":37850,"journal":{"name":"Journal of Industrial Engineering International","volume":"1965 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91319714","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}

This study investigates the impact that marketing via social media has on the value of a brand. Building on the theory of uses and gratifications as well as the concept of brand experiences, our hypothesis was that the relationship between social media marketing activities and consumer benefits, such as brand awareness and value consciousness, is mediated by consumer experiences with brands, brand experiences, and participation in online communities. A survey with a total of 350 consumers who use social media and are actively engaged in branding was carried out, and the data collected from the survey were analyzed using a variety of statistical tools. The findings indicate that social media marketing had a significant impact on all aspects of the brand experience, including value consciousness, brand awareness, and brand experience.","PeriodicalId":37850,"journal":{"name":"Journal of Industrial Engineering International","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88895186","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}

Eliya Lubis saat ini belum menerapkan perencanaan produksi yang baik untuk pelaksanaan produksi, pengusaha roti kacang melakukan perencanaan produksi hanya berdasarkan jumlah permintaan sebelumnya. Usaha ini sering dihadapkan suatu keadaan dimana adanya suatu ketidak pastian produk dengan banyaknya permintaan, karena banyaknya permintaan bersifat fluktuasi maka pengusaha roti kacang perlu memperhatikan kesesuaian banyak produk dengan permintaan konsumen agar tidak terjadi kerugian akibat produk yang berlebih dan terlalu sedikit. Berdasarkan permasalahan yang ada, diperlukan suatu perencanaan produksi menggunakan metode Goal Programming untuk pengoptimalan produksi roti kacang dengan bantuan software LINDO 1.6, metodeGoal Programming ditujukan untuk mengatasi masalah dengan lebih dari satu tujuan.
