Dynamic Workflow Design Model Manual Design of workflow –Tedious, –Not suitable for: –Inter-agency workflows Design process requires expert knowledge on government regulations across several agencies –Customized workflows Need to cater to many variations  Dynamic/automatic Design is needed:

Example 1: Inter-agency Services A developer wishes to build a warehouse complex in a vacant lot on the bank of the Hackensack River in Little Ferry, New Jersey. He is interested in a lot size greater than equal to 15 acres. Zoning certificates, Army Corps of Engineers Section 10 or Section 404 permit, NJDEP Waterfront Development Permit, Stream Encroachment Permit, Water Quality Certificate, Riparian Grant, etc.  Comprehensive knowledge required for integrated inter-agency workflow design: (services, regulations)

Example 2: Customized Services User Profile –Mary: sole proprietorship, convenience store, no employees –John: Incorporated, Auto boy repair shop, 3 employees file for FEIN enter new business Register business for taxes obtain Employer reg number apply for Employer Insurance Div.

Complete Predefined Static Workflow Static predefined tasks and dependencies –Business processes have to be fully specified in advance –Specifying all possibilities is not possible or error prone - user preferences differ greatly, so hard to predict –Hard to debug –Not easily modifiable or adjustable for different user preferences Business rule changes require redesign schemas –Hard to incorporate business policy changes –Agent A’s local change =split (if x>400 then A1, else A2) Competitive markets force companies to offer solutions tailored to the needs of their customers Customized workflow Composition, Automatic/not manual

Our Approach: Dynamic Workflow Generation Model for Inter-agency Workflows Domain Services hierarchy Regulatory knowledge base User Profile Model Composition Rules (Expert’s knowledge) Rule-based selections and integration of component services

Land Preservation and Development Meadowlands District under intense development pressure A wide range of projects being proposed (turn landfills into parks, build hotels/offices, etc.) 800 Permit requests per year Approx Open cases per year

Objectives Combine GIS and WF technologies to assist development/preservation project management –Assist outside organizations and individual developers in identifying areas of interest by presenting alternate WF –Assist NJ Meadowlands Commission in managing the permitting and reporting processes

GIS+Workflow = Geospatial Workflow Integration of Explicit Geodata –Explicit Geographic coordinates (loc) with various data set (Zoning Land Use, Parcel, Traffic Patterns, Landfill and Contaminated sites, Demographics, Business Establishment, etc.) Visualization for analysis, planning –GIS Coverages/Layers  Include Implicit Geodata –Geospatial Regulations (e.g.Zoning Regulations), –Services/processes (e.g. Permitting services)  Dynamically generate integrated services (I.e. workflow) = Geospatial Workflow

Geospatial Workflows Location dependent component-based composition model –Tasks and dependencies are associated with a particular geographic location and its attributes Geodata and geographic rule driven customization model –GSWF are customized based on current geographic characteristics, and users preferences and goals –As such characteristics change (e.g, re-zoning) GSWF should automatically adapt

System Architecture

User Profile Gathering Type of Project –(Preservation, Mitigation, New Development, Re-Development/Alteration) Lot Ownership –(Owned, To be acquired) Project spans more than one lot –(Yes, No) Type of business or other activity – (Corporate Offices, Warehouse, Golf Course, Park, etc.) Property Drainage – (Sufficient, Insufficient)

Geospatial Regulations as Rules IF (lot area < 10,000 sq ft ) OR (lot width < 100 ft) THEN add(variance) IF (fuel tanks and container involved) THEN obtain( Proof of Compliance with NJDEP tank regulations) IF (another gas station located closer than 1000 ft) THEN deny( permit) and prompt (pick another location) IF (solid waste site) THEN require (soil erosion plan permit) and require (zoning certificate for excavation) IF (property affects county road or drainage structure) THEN apply for( County site plan approval) IF (expected land disturbance > 5,000 sq ft.) THEN obtain (Soil Conservation District Approval)

Geospatial Regulations as Rules IF (loc, in, across(river, lake, pond..) OR =(100yr flood plaine of any stream)) Then obtain (Stream Encroachment Permit) IF (loc, =( upland) AND within (500ft of tidal waterfront)) Then get (Waterfront Development Permit) IF (loc, in(HMDC district)) Then get (development approval by HMDC)

Example: Development GSWF Profile: Choose a site to develop a warehouse in various vacant lots  Coverage with vacant lots activated A Map-based Selection/choice of a parcel: Choice A: B: … C: …. Zoning type (light residential) Land Use (Two family home) Lot size is less than 10,000 sq. ft. Obtain Soil Erosion Permit Certificate of Zoning For Excavation Proof of Compliance On Tank Regulations Certificate of Zoning for Development File for Lot Size Variance WF2 WF3WF1

Example: Development GSWF County Site Plan Approval Conformance with Flood Insurance Rate Maps Confirm 50ft. Buffer Strip Apply for ZoningCertificate NJ DEP Proof of Compliance Permit for Construction and Operation of a temp. sewage facility sewage facility SiteInspection ZoningCertificate

Prototype

Benefits Selecting different lots automatically produces several GSWF from which a project manager can choose Once a GSWF is chosen, it can be put into action –Project Managers are guided through each step of the WF –NJ Meadowlands Commission can track progress of the workflow, anticipate workload, etc. GSWF are dynamic so as Geodata change, WF are automatically updated

Year 3: Plan Handling Dynamic changes in workflow Prototype: Integration with all components

Visualization of Geospatial Regulations N. Adam, V. Atluri, Francisco Artigas, Pietro Mazzoleni, Soon Ae Chun, Customized Visualization of GeoSpatial Government Regulations (to be submitted to The Second National Conference on Digital Government, May 2002)

Problem Statement What are the possible locations for my business (in accordance with all zoning regulation)? How can I identify the appropriate permits I have to obtain?

Example An entrepreneur wants to open an Autobody shop in a vacant lot on the bank of the Hackensack River. (1) USER PROFILE (1) USER PROFILE: Bigger than 1000 square feet In an area with high volume of traffic Not Closer than 2000 feet to a competitor

Example (2) ZONING REQUIREMENTS (2) ZONING REQUIREMENTS: Autobody is permitted only in Neighborhood commercial zone Light industrial … Highway commercial Zone as exceptional Use The minimum lot area shall be square feet If closer to a residential area, the rear yard distance has to be at least 25 feet instead of the usual 20 feet. In Neighborhood commercial zone an autobody cannot be built closer than 1000 feet to a competitor

Example (3) GIS PRODUCTS WE DEVELOPED (3) GIS PRODUCTS WE DEVELOPED: Zone Visualization Lot/Block and parcel Information Competitors Location Traffic volume

Current Status Zoning Regulations –Rules are divided by Zone area GIS Products – Information about the Area (zone-name, lot dimension)… – Information about the competitors WHAT IS LACKING: Zoning Regulations that apply to the area WHAT IS LACKING: Information organized by type of Business

Proposed Solution Customized zoning rules retrieval Visualization of the permitted zones for a particular business Dynamic Evaluation of Buffer and Lot-size requirements Automatic extraction of the relevant permits and the sequence for completing the procedure

Customized Zoning Regulation Regulation based on the USER PROFILE requirements Show me ALL the Rules that apply if I want to Open an Autobody shop in a High-way Commercial Zone, and I would also like to sell retail products.

Customized Zoning Regulation Autobody shop Neighbor commercial

Business Location Visualization Geographical Map Customized according to the user’s preferences and the zoning rules Show me the zones in the map where I can open an Autobody shop according to the zoning rules; in two cases: (1) with no special permit requirement and (2) where some special permits such as variance are required

Business Location Visualization Autobody shop

Size and Buffer Regulation Size and Buffer Regulation Visualization of the lots that satisfy dimension and distance-based requirements Lots bigger enough to include my business Distance from a competitor Other rules specific for an area like Waterfront Distance Requirements

Size and Buffer Regulation Size and Buffer Regulation Autobody shop Neighbor commercial

Waterfront Regulation Autobody shop Neighbor commercial

Tools ESRI ARC IMS (Internet Map Application Server) –Map Data server Oracle DBMS –Rules database and profile session info Perl and Java –Back end database/GIS/Web connectivity Client Web Browser interface + Javascripts

Future Work Integrate the prototype into the MyNJbusiness System Extension of the Zoning Regulation database for increasing the portability Add more information in the map (traffic, land price, etc) Considering the non-vacant lots. Enhancement of the Prototype functionality adding more map-interaction
