Thereby, BPS creates value as it decreases the inventory buffers between process steps and enables organizations to balance demand uncertainties.
Without this focus, it would be all too easy to make improvements but not to convert this efficiency into cash by lowering inventory buffers in a controlled manner.
The difference is that today's inventory buffers are not mountains built to a "just-in-case" standard, but carefully calculated as part of a distribution network able to respond to real-time conditions on the battlefield.
The Lean paradigm uses approaches that are relatively novel in health care, such as management of minimal inventories, minimal buffers of work-in-process and minimal latitude in planning [ 9].
Also, the markets are less able to absorb changes of investor views.Because of balance sheet concerns and regulatory pressure, banks are less able to take on big inventory positions to buffer flows even when prices look attractive.
Two production inventory systems with buffer are developed.
Further on, it is influenced by the accumulation process of production material stocked into buffers along the line; hence, the buffer inventory level is also a relevant variable that has to be considered when assessing the throughput of the line.
The buffer inventory level should provide the proper isolation time before the buffer becomes empty, so that, during this time, a maintenance intervention can be carried on at a failed machine upward, without causing a propagation of the effect of the failure in the machines downward (the so called 'material starvation').
For instance, several organizations facing uncertainty would build flexibility in the supply chain taking the form of buffer inventory, a larger supply base, or excess capacity (Sawhney, 2006) all of which requires more resources to implement or manage by the same token less resources are available for environmental management.
The optimization objectives are generally set to minimize the inventory cost, or minimize buffer sizes and time of material waiting prior to being further processed (Tserng et al. 2006; Walsh et al. 2004; Xu et al. 2016).
