This study is conducted to developed innovative production planning and control strategies to manufacturing industries so as to improve production performance and competitiveness of basic metal sectors Though the study was conducted through field observation and questioner used as primary data and literature review on research articles, books, and electronic-sources which used as secondary data. While the questioner and filed observation data collection were done from two selected Ethiopian basic metal industries. Since the collected data were employed by both using descriptive and empirical analysis. Waste in the production process, poor plant layout systems, defective products, improper material requirement planning, deficiency on control and monitoring systems, insufficient inventory control, poor workflow strategies, null warehouse management systems, problems in information systems and information management strategies were investigated as the main challenges of developing the nation basic metal industries. As a result of these challenges, the performance and global competitiveness of local basic metal industries are poor and weak. As well the literature’ finding endorse that production planning and controls have gradual advancement in developed manufacturing industries but it is found to be at its infant stage in developing manufacturing industries. Due to these challenges and weak performances on the developing firms, the entire production process on the industries was declining, and then they approach to die. Though the new product planning and controlling strategies can bridge the gap and birth will begin within proper implementations of the model to basic metal industries. تفاصيل المقالة

The selection and implantation of sufficient and appropriate continuous improvement strategy are the key success factors for improving firm performance and enhancement of competitive advantage on manufacturing industries. As a result special role are given to Continuous improvement programs such as Supply Chain Management (SCM), Six-Sigma, Total Quality Management (TQM), Kaizen, Just-in-Time (JIT) and Total Productive Maintenance (TPM) in a production system, which attain sustainable business environment and competitive advantage. Thus, the aim of the study is to study the challenges and trends of global competitiveness of basic metal industries, investigates the way of integrating continuous improvement tools and then developed an integrated continuous improvement model from TQM, JIT, and SCM to improve the global competitiveness of steel and metal industries. From numerous contentious improvement programs, we have to emphasize integrated SCM, JIT and TQM implementation on basic metal industries to improve competitive performance. Mainly the study was conducted through field observation, questioner, company reports used as primary data and literature review of research articles, books, manuals, magazines, and electronic-sources, which used as secondary data. The survey data is analyzed using descriptive analysis, SPCT (fishbone diagram).The result found that poor supply chain system, workforce, raw material uncertainty, energy fluctuation, outdated technology, manufacturing systems, financial and logistics problems were identified as the obstacles and influence the Ethiopian basic metal industry performance and global competitiveness. Thus, to tackle the problems an integrated continuous improving model was developed to improve the performance and global competitiveness of basic metal industries. تفاصيل المقالة

این پژوهش با هدف بررسی تأثیر خرد رهبران بر رفتار شهروند سازمانی با نقش میانجی فرهنگ سازمانی در دانشگاه آزاد اسلامی شهر تهران انجام شد.روش پژوهش برحسب هدف کاربردی، از نظر روش گرداوری داده ها توصیفی- همبستگی و همین طور از نظر نوع داده کمی بود.جامعه آماری پژوهش اساتید هیئت‌علمی دانشگاه های آزاد شهر تهرانبودند که با استفاده از محاسبه حجم نمونه در معادلات ساختاری و روش نمونه گیری تصادفی خوشه ای مرحله ای، تعداد 700 نفر به عنوان حجم نمونه انتخاب شد که همگی اعضای هیئت‌علمی تمام‌وقت بودند. به منظور گرداوری داده ها از سه پرسشنامه استاندارد خرد آردلت (2003)،رفتار شهروند سازمانی اورگان و کانوسکی (1996) و فرهنگ‌سازمانی دنیسون (2000) استفاده شد.پس از جمع آوری پرسشنامه ها، توصیف داده ها از طریق میانگین، انحراف معیار و ... از طریق نرم افزار Spss-21 و استنباط آماری داده ها از طریق مدل‌سازی معادلات ساختاری و به کمک نرم‌افزار LISREL-v8.80 انجام پذیرفت.ویژگی های فنی پرسشنامه شامل پایایی، روایی همگرا و روایی واگرا بررسی گردید.ضرایبمسیر و ضرایب معناداری نرم‌افزار برای بررسی فرضیه های پژوهش مورد استفاده قرار گرفتند.نتایج نشان داد، درجه تناسب مدل ارائه شده با توجه به مؤلفه های پژوهش مناسب بود؛ هم چنین خرد رهبران بر رفتار شهروند سازمانی با نقش میانجی فرهنگ‌سازمانی تأثیر داشت. تفاصيل المقالة
