Round 1 of Littlefield Technologies was quite different from round 2. We started the game with no real plan in mind unlike round 2 where we formulated multiple strategies throughout the duration of the game. Starting off we could right away see that an additional machine was required at station 2 to handle the dual processing load from station one and three. We purchased a machine for station 2 as soon as we gained control over the factory. Looking back now I can see that this could have been a risky

APPENDIX APPENDIX. CALCULATING NATIONAL LOGISTICS COSTS Logistics costs are an important factor affecting the competitiveness of both firms and nations. Firms can enhance their market competitiveness by reducing their logistics costs‚ thus lowering the total costs of goods and services. Greater market competitiveness of a nation’s firms can then give rise to greater national industrial competitiveness on a global scale. Total logistics cost analysis is the key to managing the logistics function

NPSHA in the system is calculated as : NPSHA = Terminal Pressure in the vessel (in guage) (+) Static Head of fluid above pump centre line (see note). (+) Atmospheric Pressure (-) Vapour Pressure of liquid at pumping temperature (-) Friction loss in suction piping up to pump centre line consisting of the following : Entrance and exit losses Loss in suction strainer Loss in control valves‚ instruments‚ exchangers etc. if any Line losses Note : a) The height of liquid in the vessel
