This research elaborates decision models for product innovation in the early phases, focusing on one of the most widely implemented method in marketing research: conjoint analysis and the related conjoint-based models with special focus on heuristics programming techniques for the development of optimal product innovation. The concept, potential, requirements and limitations of conjoint analysi...

Software Product Line Engineering (SPLE) is a relatively new software development paradigm to improve systematic software reuse. There are two key assets underpin the software product line (SPL) development: a feature model and a reference architecture. To deal with complex crosscutting behaviours in SPLs and also manage the impact of nonfunctional requirements (NFRs), we propose an aspect-orie...

Let A and B be nonnegative matrices. A new upper bound on the spectral radius ρ(A◦B) is obtained. Meanwhile, a new lower bound on the smallest eigenvalue q(A B) for the Fan product, and a new lower bound on the minimum eigenvalue q(B ◦A−1) for the Hadamard product of B and A−1 of two nonsingular M -matrices A and B are given. Some results of comparison are also given in theory. To illustrate ou...

Infrared Functional Imaging was applied to the study of Raynaud’s Phenomenon obtaing a simultaneous assessment of the thermal properties of all five fingers of both hands of a group of patients with respect of a control group. The method is based on the use of high-resolution telethermography imaging and allows identification of objective parameters from the re-warming curves of finger immediat...

Watermarking is done in digital images for authentication and to restrict its unauthorized usages. Watermarking is sometimes invisible and can be extracted only by authenticated party. Encrypt a text or information by public – private key from two fuzzy matrix and embed it in image as watermark. In this paper we proposed two fuzzy compositions Product-Mod-Minus, and Compliment-Product-Minus. Em...

Variability in a Software Product Line (SPL) is expressed in terms of a feature model. As software development efforts involve increasingly larger feature models, scalable techniques are required to manage their complexity. Furthermore, as many stakeholders have a vested interest in different aspects of a feature model, modularity techniques are required to independently expresses their views o...

This paper examines the rationale underlying periodic price promotions, or sales, for perishable food products by supermarket retailers. Whereas previous studies explain sales in a single-product context as arising from informational, storage cost, or demand heterogeneity, this study focuses on the central role of retailers as multi-product sellers of complementary goods. By offering a larger n...

  A product life cycle is the life span of a product in which the period begins with the initial product specification and ends with the withdrawal from the market of both the product and its support. A product life cycle can be divided into several stages characterized by the revenue generated by the product. This study investigates inventory control policies in a manufacturing system for a si...

Product based organizations have diverse product offerings that meet various business needs. The products are in turn integrated to create integrated product suites. Rigorous product engineering is a must for creation of high quality integrated software products. Adequate measures must be taken to improve quality of the integrated product before every release of its module or sub-product. It is...
