Although only one type of operation is called continuous flow, in practice most types, even those employing several discrete stages, aspire to continuous flow.
1. Just-in-time (JIT)
1.1 Introduction: Moving materials swiftly through processing reduces cost – fewer handing and storage charges, lower inventory, lower work-in-progress levels (reducing control problems), and shorter lead times.
1.2 Background: The JIT approach was pioneered in the 1970s at the Toyota motor company. In Japan, JIT is often called “TPS,” for Toyota production system.
1.3 Principle: Elimination of waste and responsiveness are pillars of JIT. The satisfying of demand as it arises, so there is neither the waste of having finished goods waiting in store for an order that may never come, nor the unresponsiveness of making a customer wait.
2. “Pull” systems
2.1 Introduction: Materials are pulled through the supply chain ultimately by customer request. The idea is not to hold more than the minimum inventory and to make just what is needed when it is asked for and not before.
2.2 Principle: Synchronized manufacturing, highly responsive and low-stock system. It is to eliminate buffers and solve the problems being buffered against – unreliable suppliers, machine breakdowns, labor inefficiencies, defective material, and so on.
3. Lean production
3.1 Introduction: By using the “pull’ system, the result is a dramatic fall in costs, since the removal of such problems and

Sediment Transport and Ritter et. Al Essay

characteristics of the depositions. Sediments are particles of former rocks which have been eroded over time. The eroded material is then transported by different processes onto the landscape sometimes over very far distances. There are three major types of sediments, one are clastic sediments which are composed of rock particles. Additionally Sediments form from organic materials such as dead organism and other collections of organisms which are often organic rich and contribute to a more fertile…

right time, also from raw materials extraction to final purchases. Supply Chain management focuses on planning and forecasting, purchasing, product assembly, moving, storage, distribution, sales and customer service. SCM is the active management of supply chain activities to maximize customer value and achieve a sustainable competitive advantage. The organizations that make up the supply chain are ’linked’ together through physical flows and information flows. Physical flows are the most visible piece…

What Is Material Record

Sam Nord-Stephens 12/9/12 Intro: Material records are all the materials found at an archaeology sight or used within a culture. This can consist of artifacts, built structures, garbage, plant remains, animal remains, drawings, music or audio, pottery, materials such as plastic or glass that are used for different functions, clothing, etc. Material records are used to better understand past cultures and allow archaeologists to infer or discover major characteristics of these societies…

Volcanic: Volcano and Basaltic Lava Essay

(over 70%), is very viscous and forms short, thick flows. Basaltic (mafic) lava, with a lower silica content (~50%), is more fluid and may travel a long distance before congealing. Dissolved gases tend to make magma more fluid, and as they expand, provide the force that propels molten rock from the volcano. 2. The materials associated with a volcanic eruption include (1) lava flows (pahoehoe flows, which resemble twisted braids; and aa flows, consisting of rough, jagged blocks; both form from…

Essay about Erosion And Deposition River Features

waterfalls form. Waterfalls form when a sudden drop is met in the course of a river. This drop may be a result of a drop in sea level, erosion by ice or earth movements. But usually a waterfall is formed when a river meets a layer of harder rock, then flows over a layer of softer rock. The softer rock underneath is eroded more quickly than the more resistant hard rock, resulting in an undercutting below the harder rock. Over time, as the undercutting increases, an overhang of hard rock is formed, and…
