Delivery reliability

While raw material supply is usually taken for granted, some models also include vendor selection, vendor capacity constraints or vendor delivery reliability (e.g., Martel et al. 2005 Vidal and Goetschalckx 2000 Vidal and Goetschalckx 1996). 

As a consequence of the increased focus on reduction of carbon emissions to the environment, more and more offshore oil and gas installations are now being analyzed for and also realized with power supplied from the onshore Norwegian power system. These projects, from the early studies to realization, involve several challenges that have to be managed by the oil and gas companies. Central challenges are the offshore installation power delivery reliability and the impact these large loads have on the existing onshore power system. 

The need for powerful analyses tools is therefore obvious. Tools for power flow calculations, dynamic analyses etc. are some of the most important tools for the TSO. In addition, to be able to analyze the load delivery reliability, a suitable power system reliability analysis tool is needed.

Since a power system is dynamic, variables such as power demand, power production, load flow, and short circuit levels will continuously change. The same changes also apply for the power delivery reliability results at each load branch. It is important to be aware of this fact, when operating a power system. Different action and changes in a power system will change the reliability of power delivery. Power grid operators, power system planners and the new customers to be connected to the existing power system should be aware of this and make their decisions based on the best information available. 

Order winners—Those competitive characteristics that cause a firm s customers to choose that firm s goods and services over those of its competitors. Order winners can be considered to be competitive advantages for the firm. Order winners usually focus on one (rarely more than two) of the following strategic initiatives price/cost, quality, delivery speed, delivery reliability, product design, flexibility, after-market service, and image. 

Conjoint analysis and related techniques are directly relevant to the marketing-operations interface because (1) they address the trade-off between customer satisfaction, which determines an upper-bound on product price, and the pro-duction/distribution cost of the product, and (2) they facilitate acquisition of empirical evidence to evaluate operational strategies. For instance, Lindsley et al., 1991 used conjoint analysis to quantify the tradeoffs that retailers are willing to make among price discoimt, speed of delivery, delivery reliability, number of titles carried in inventory, offered by book distributors. The customer satisfaction equation, estimated by the authors, suggests that a decrease in the discount rate of 0.38% offsets a one-day reduction in delivery time and an increase of 1% title filling rate saves 0.16% discount rate. The equation...

Zi represents the material price criterion, represents the delivery reliability criterion, and Z3 represents the quality criterion, x, is the quantity to be purchased from the /th supplier. N denotes the number of candidate suppliers, v, indicates whether the /th supplier is included in the supply network. and limits minimum and maximum total order quantities for the/th supplier, respectively, pj is the net purchase price per unit for /th supplier. A, is the percentage of late items for the /th supplier, fij is the percentage of items rejected for the /th supplier. 

Delivery reliability It refers to the capacity to deliver the products to the customer on promising criteria (time, quantity, location, etc.) (Celebi et al. 2010 Stock et al. 1998 Supply Chain Council 2012).

The most often desired service element is delivery time, followed by quality, after-sales service, delivery information and price. Assuming that after-sales service and delivery information can be combined to flexibility, it is discovered that all of the successively listed elements (e.g. order accuracy, availability or delivery reliability) could be allocated to one of the first elements, which therefore are considered as primary or strategic needs, namely delivery time, quality, flexibility and price. 

PC Manufacturing Inc. has identified customer requirements which are ranked from product quality, price, product availability, and delivery reliability to service quality. Products can be ordered by means of different distribution channels via direct orders by mail or telephone, on its online platform, or through retailers.

To provide a basis for analyzing our framework within a realistic setting, an order-to-cash workflow by a medium-sized company in Germany was chosen. The example workflow is depicted in Figure 2. In our case we want to asses the resilience and the delivery reliability of this workflow even under turbulent situations. It is taken to evaluate the introduced approach for resilience assessment.
