Ready mixed concrete (RMC) placing is a major on-going operation on construction projects in many countries. Evaluating the productivity of a ready mix concrete batch plant is one of the most challenging tasks of a plant manager and engineer, since it involves a lot of uncertainties, thus risks. Delivering ready-mixed concrete (RMC) efficiently to construction sites is a practical concern and one of the most challenging tasks for RMC batch managers. Batch plant managers must consider both time and order factors in order to set an RMC truck dispatch schedule that successfully balances batch plant (supplier) and construction site (customer) priorities. This project develops a transportation model to determine the solutions for RMC truck dispatch scheduling. The model takes into consideration uncertainties as well as unexpected situations such as truck breakdowns during delivery. This project is highlighting the study of Batching plant productivity without affecting the quality of concrete by prolonged recapitulation of various batching plants sites for the factors which could affect the output of subject batching plant and decry and predicament shooting of such factors in time. In this paper Past studies based on Productivity of batching plant is studied in detail.
