Abstract A phenomenon resulting from a computationally irreducible (or incompressible) process is supposedly unpredictable except via simulation. This notion of unpredictability has been deployed to formulate recent accounts computational emergence. Via technical analysis, I show that irreducibility can establish the impossibility prediction only with respect maximum standards precision. By art...

The high cost of lenient return policies force consumer electronics OEMs to look for ways to recover value from lightly used consumer returns, which constitute a substantial fraction of sales and cannot be re-sold as new products. Refurbishing to remarket or to fulfill warranty claims are the two common disposition options considered to unlock the value in consumer returns, which present the OE...

We consider the problem of outsourcing warranty repairs to outside vendors when items have priorities in service. The manufacturer has a contract with a fixed number of repair vendors. The manufacturer pays a fixed fee for each repair done by a vendor which is independent of the repair type and priority class but depends on the vendor. There are a fixed number of items under warranty, and each ...

For products sold with a warranty, preventive maintenance (PM) actions by either the manufacturer and/or the buyer has an impact on the total cost for both parties. In this investigation, we use a model to study the effect of PM carried out by the buyer on non-repairable items sold under a free replacement renewing warranty, and a penalty will be incurred by the buyer if the item fails before t...

The objective of this study is to develop a warranty servicing strategy, based on imperfect and minimal repairs, that minimises the total warranty servicing cost. For pre-specified degrees of repair, the expected warranty servicing cost is minimised by optimally partitioning a two-dimensional rectangular warranty region into n disjoint subregions. We numerically illustrate the imperfect repair ...

The environmental sustainability and business benefits of end-of-life products have led to worldwide growth in the remanufacturing market. However, customers are often sceptical about quality durability remanufactured products. To ensure a risk-free customer experience, dealers carry out some upgrading actions on most critical components offer reasonable warranty period at time resale. It is cr...
