Fashion chain distribution: Simulation of a Brazilian case
Show/Hide Abstract
Brazil is one of the developing countries comprise the acronym BRICS, which has a high potential to represent the production and consumption accounts for 50% of global GDP.
Distribution and chains fashion chains are dynamic and show good numbers of growth in Brazil. The distribution of products in Brazilian territory needs complex studies because much expensive this job, for its continental dimensions. The solutions are not unique, and the decisions needs to be made based on effective means to generate good results. This paper presents a case study of the Spanish fashion company that intends to distribute its products in Brazil. The study is done using simulations, in which possibilities are presented for the lowest cost in relation to best delivery time of the product, depending how the necessity of the company is at the moment of the exportation, from the air and road modes. Analyze there are several possible combinations of results depending on the business need for the moment. With the simulation tool is possible to construct various scenarios and pick from them. In this study, the conclusion is adopted from logistics decisions based on costs and simulation tools can be successful team when it comes to distribution of fashion with the management being treated as a supply chain.

Effective Edge Detection: A Comparative Study
Show/Hide Abstract
Edge detection is the most important step in image segmentation and analysis. Statistical distributions are commonly used in this field.
In this paper we present a comparative analysis between Beta, Log-Normal and Gamma distributions in terms of accuracy, complexity and computational performance.
It was found that Log-Normal was best in terms of accuracy however more complex. Beta and gamma distributions were similar in both accuracy and performance
for they both deal with asymmetric data. Anew Convolution from
these distribution which benefits from there advantages and avoids there shortcomings is proposed and tested.

Using Tags for Business Process Enrichment
Show/Hide Abstract
This paper discusses the use of tags for enriching business
processes with various details obtained at design- and run-time. In ad-
dition to anchoring tags to tasks that constitute a business process,
tags are connected to each other through specific data dependencies
that in fact, already connect tasks to each other. These dependencies
include prerequisite, parallel prerequisite, and parallel. Types of tags
proposed during enrichment are social, resource, location, and tempo-
ral. Business process engineers and end-users (executors) fill out the
tags with the necessary details and ensure that these details are for-
warded from one tag to another, when appropriate. The objective is to
help reduce time and efforts put into completing the remaining tags.
At design time relations between tags include unidirectional-transfer-of-
final-details, unidirectional-transfer-of-partial-details, and bidirectional-
transfer-of-partial-details. At run-time relations between tags include
strong-trigger, weak-trigger, and meet-in-the-middle trigger. A running
scenario along with a demo system are also discussed in this paper.

Operational Profile Modeling as a Risk Assessment Tool
for Software Quality Techniques
Show/Hide Abstract
A major share of software project investment is assigned to activities
concerning the detection and removal of defects. Software
project managers tend to apply the most efficient QA techniques to
assure low defect density within their software project. However,
the criteria of selecting a QA technique based on its efficiency is
not always safe and cost effective. Software defects vary in their
severity in terms of the magnitude of their negative impact on both
the testing process and the whole project. Some defects would
make intense implications if it passed to the operational use as it
belongs to significant functional components of the software. The
consideration of potential risk with some defects types should be
taken into account when selecting a QA technique to avoid future
failure. In this paper, we build on previous work of software quality
optimization by proposing a model whereby QA decisions are
normalized by the risk associated with their defects detection and
removal activities.

Web-based Tool for Preliminary Assessment
of Wind Power Plant Design
Show/Hide Abstract
Designing of reliable and cost-effective industrial wind power plant
is a prerequisite for the effective use of wind power as an alternative resource.
The design of a wind power plant includes the determination of type, number
and layout of wind turbines for given site area. Preliminary assessment of design
project will decrease the possibility of costly errors at practical realization
of the project.
A Web-based tool for preliminary assessment of wind power
plant design project is described. An original algorithm with two branches ("iterative"
and "intelligent") is at the core of this application. The proposed tool
can be used to simulate and evaluate different wind power plant design projects
by preliminary estimation of energy output and associated costs. The applicability
of the described tool is demonstrated by real data for wind turbines and parameters
of the wind site.
