The historic core of Rosetta, Egypt, is a possible nomination for UNESCO World Heritage status. However, the enduring controversy over the conservation scheme for Rosetta’s old market has highlighted the difficulties in reaching a satisfactory decision. The challenge lies in determining the best location for relocating the market without affecting locals’ life and culture of locals as part of the urban built heritage.

The main objective of this study is to present a model of decision-making criteria, which can have many applications in heritage conservation decision making for preserving heritage in historic cities that are distinguished by religious, societal and economic activities.

A Multi Criteria Decision Making model (MCDM) is a framework for project selection and is developed utilizing the Technique for Order of Preference by Similarity to Ideal Solution; (TOPSIS) method, in reference to UNESCO guidelines, and Space Syntax analysis. The joint analytical framework helps to select the best location for the market that would promote the development of the area while also preserving the identity of the historic core.

By adopting this proposed joint model, it is possible to meet social needs during urban development. Thus, the outcome of this study is to achieve a balance between the dual elements that the community works to achieve its integration with the historical urban fabric and at the same time allows development and tourism and tries to exist and takes part of the development plan, and promotes the identity of the city in terms of heritage, commercial and cultural activities as well as benefit from achieving development.

This model can be tested against development plans for cities of historical economic values in a variety of circumstances extended with other specific criteria related to the context of the case study under analysis and development study, in addition to UNESCO guidelines to ensure its reliability.

An urban conservation and development policy will enable the city’s authorities to register its historical core as a UNESCO World Heritage Site. This research outcome validates a model for decision-making assessment that can be utilized to assess historic cities that include historical commercial activities.

埃及罗塞塔的历史核心可能被提名为联合国教科文组织世界遗产。然而，关于罗塞塔旧市场保护计划的持久争议凸显了达成令人满意的决定的困难。挑战在于确定重新安置市场的最佳位置，同时又不影响作为城市建筑遗产一部分的当地人的生活和文化。

本研究的主要目的是提出一个决策标准模型，该模型可以在遗产保护决策中广泛应用，以保护以宗教、社会和经济活动为特色的历史城市的遗产。

一个多目标决策模型（MCDM）是项目选择的框架和开发利用技术的偏好逼近理想解决方案的订单; (TOPSIS) 方法，参考联合国教科文组织的指导方针，以及空间句法分析。联合分析框架有助于为市场选择最佳位置，以促进该地区的发展，同时保留历史核心的特性。

通过采用这种建议的联合模式，可以满足城市发展过程中的社会需求。因此，这项研究的结果是在社区努力实现其与历史城市肌理的融合的双重要素之间取得平衡，同时允许发展和旅游，并试图存在并参与发展计划，并在遗产、商业和文化活动方面提升城市的身份，并从实现发展中受益。

除了教科文组织的指导方针外，该模型还可以针对具有历史经济价值的城市在各种情况下的发展计划进行测试，该计划扩展了与分析和发展研究中的案例研究背景相关的其他特定标准，以确保其可靠性。

城市保护和发展政策将使城市当局能够将其历史核心登记为联合国教科文组织世界遗产。该研究成果验证了决策评估模型，该模型可用于评估包含历史商业活动的历史城市。
