Inventory planning

Distribution planning covers transportation and inventory planning in the global value chain network from a company perspective. Distribution planning has to balance volumes and flows in and between the respective sales, production, distribution and procurement locations. Significant lead...

Concluding, the areas mostly impacted by the global scope such as global material flow planning and multi-period transport and transit inventory planning are covered best by global models (s. table 15). 

The coverage shows that models rather focus on specific requirements areas and functions in value chain planning. It turns out that some requirements such as future inventory planning and process throughput smoothing are less investigated than others.

Distribution planning described in subchapter 5.5 handles multi-period transportation time and transit inventories as global material flow planning. Moreover, static and dynamic inventory planning is supported. 

The relaxation ton counter p sums relaxation ton counters in sales, inventory and transportation. The individual relaxation ton counters are presented in more detail in the respective sales, transportation and inventory planning subchapters. 

Final material cost rates and product value rates are determined based on the indexed material cost and product value rates. Multiple indexed material cost and product value rates occur, if cyclic material flows exist in the value chain. In order to apply index-independent cost and value rates in the model for future inventory planning, the maximum value and cost rates are determined for all products, locations and periods across all value chain steps i. 

The product value rate for future inventory planning is equal to the product values at all transfer point locations. 

Finally, future inventory planning is integrated in the overall optimization process as preprocessing phase. Alternatively, it can be run independently before the optimization to ensure usage of the most recent future product values for calculating capital costs in the optimization. 

The presented approach for future inventory planning can be only a first proposal in the specific scope of this work with significant potential for further research. 

Distribution planning covers transportation and inventory planning within the network, as well as the material balance calculation between sales, production and procurement. Global transportation planning considers the lead times between continents resulting in transit inventories differentiation of sent and received transportation quantities as shown in the requirements in section 4.1.5. Inventories are managed at the defined transfer point locations either with static or dynamic boundaries. 

Transcontinental transportation and transit inventory planning during the initial planning periods need considering transportation quantities and... 

Concluding, the transportation planning model realized the planning requirements for a global value chain network with respect to global transportation send and received quantities as well as transit inventory planning. 

Future inventory planning approach to anticipate future inventory values in the value chain network based on future raw material price forecasts. 

Global transportation and transit inventory planning differentiates sent and received transportation quantity allocation cases and calculates transit inventories and capital costs on the transportation lane. 

As soon as a decision for closure is reached, a complete inventory of all equipment, parts, and supplies should be made. Using this inventory, plans can be made for appropriate disposition of each item. Many items can be resold or transferred to another mine owned by the company. In the case of large underground mining equipment, such as coal longwall units, it may be less expensive to abandon the equipment underground than to recover it to the surface. 

Detailed inventory plans and shipping schedules can be developed, taking into account forecast of demand, economic lot size and planned production capacity. These are all correlated to financial advice on costs, and a model is utilized to project the cause and effect if any of these particular items are radically modified. 

In preparing the site, a subbase of granular material is placed over a graded and compacted subgrade. If a vapor barrier is to be used, a 6.0 mil polyfilm seamless sheet should be used. The composition of the vapor barrier should be chosen to be compatible with liquid chemicals stored in the facility. Consult the manufacturer to assure compatibility of the chemical inventory planned with the barrier material chosen.
