Average production batch size

Average production batch size measures the average amount produced in each production batch. Large batch sizes will decrease production cost but increase inventories.

Batch size shipped from each supplier to each store = 40,000 units Number of shipments/year from each supplier to each store = 960,000/40,000 = 24 Annual trucking cost for direct network = 24 X 1,100 X 4 X 8 = 844,800 Average inventory at each store for each product = 40,000/2 = 20,000 units Annual inventory cost for direct network = 20,000 X 0.2 X 4 X 8 = 128,000 Total annual cost of direct network = 844,800 + 128,000 = 972,800... 

Consequently, SC2 is able to optimize the utilization of its production facilities and save set up costs. As Figure 6-3 indicates, batch sizes increases at average by 5%, 0.5% and 0.5% for and respectively. Thus, 100 CHF can be saved... 

If the particles are all of the same size, and each particle acts as a batch system, the fraction of solid reactant B unconverted at the reactor outlet, 1 — /B(f), is the same for a particular residence time t. The contribution of particles with this residence time to the (average) fraction unconverted at the outlet, 1 - /B, is the product of 1 — /B(f) and the fraction of particles with residence time t to t + dt, which is E(t)dt. By integrating over t, we obtain the following form of the SFM, which is equivalent to that in equation 13.5-2 ... 

The flow scheme of the process(17) is represented in Fig. 2. The required throughput rate of 5 kg Pu/day is obtained in a batch-type operation, where a 5 to 10% substoichometric oxalate precipitation is performed by adding solid oxalic acid to a 3 M HNO - 100 g/L Pu(NO3) 4 solution at 80°C in about 2 hours. Up to 95% of the Pu is precipitated as uniform crystals of 20 yum average size and filtered. After washing and calcination, the average analysis of this product shows less than 1000 ppm total metallic impurities. When evaporating the filtrate to about 5% of its original volume, nitric acid is recovered, and most of the oxalic acid is destroyed. This results from sump temperatures of up to 123°C and the presence of Pu(VI). 

After untangling the polymer strands of the other sample which was formulated into a good product, it was shown to consist of a different group of three molecules (see Fig. 2-16 b). The first was 2 in., the second was 4 in., and the third was 6 in. in length. Statistically 2 in. + 4 in. + 6 in. = 12 in. divided by 3 molecules is a molecular size average of 4 in., which was the same average size as the bad batch.
