AnyLogic Professional 8.9.1: Advancing Enterprise Simulation

AnyLogic Professional 8.9.1, released in August 2024, represents a significant refinement of the world’s leading multimethod simulation software. Designed for enterprise-level modeling, this version focuses on streamlining data connectivity and expanding the manual control capabilities within the Material Handling Library. Key Features in Version 8.9.1

The 8.9.1 update introduced several high-impact features aimed at reducing development time and increasing model flexibility:

Upgraded Database Integration: AnyLogic 8.9.1 simplifies the process of connecting to external data sources. It includes built-in support for a wider variety of databases, allowing users to select from a list without manually searching for or uploading external drivers.

Manual Transporter Control: A major addition is the move() function, which allows developers to direct transporters to specific nodes without using standard flowchart blocks. This is ideal for modeling scenarios where a transporter must move to a loading point before an agent is even created.

Downtime Management: New properties for "Downtime" blocks have been added to markup elements like Conveyors, Stations, and Cranes, making it easier to simulate planned maintenance and random equipment failures.

Enhanced Callbacks: The TransporterFleet block now includes an "On destination reached" action, providing better visibility and control over fleet movement. Core Capabilities of AnyLogic Professional

AnyLogic Professional is distinguished by its ability to combine three major modeling methodologies in a single environment:

Discrete Event Modeling: Used primarily for manufacturing, logistics, and healthcare to model process flows. AnyLogic Professional 8

Agent-Based Modeling: Ideal for market simulation, social dynamics, and decentralized systems where individual "agents" (like people or vehicles) interact.

System Dynamics: Best for high-level strategic modeling, such as population growth or market competition.

The Professional edition offers unlimited model size, integration with GIS maps, and the ability to export models as standalone Java applications for clients or stakeholders. Technical Specifications & Requirements

AnyLogic 8.9.1 is built on Java 17, offering improved performance and modern coding features for developers.

2. Core Architecture and Modeling Paradigms

AnyLogic Professional 8.9.1 is built on the Eclipse Rich Client Platform (RCP) with a Java-based simulation engine. The key innovation remains its multimethod capability:

  • Discrete Event (DE): Uses process flowcharts (e.g., Queue, Delay, ResourcePool) for systems with distinct events, such as call centers or assembly lines.
  • Agent-Based (AB): Implements autonomous agents with statecharts and message passing, ideal for heterogeneous populations (e.g., consumers, vehicles, patients).
  • System Dynamics (SD): Employs stock-and-flow diagrams with differential equations for continuous, aggregate systems (e.g., supply chain inventory dynamics).

Cross-paradigm integration is seamless: an agent may contain a discrete event process, and SD variables can drive agent decision-making. Version 8.9.1 refines the event timing engine for hybrid models, reducing synchronization overhead.

5.2 Healthcare – Agent-Based + DES

A hospital emergency department simulation combined agent-based patients (each with a health state, patience level, and pathways) and discrete event resources (beds, doctors, CT scanners). The hybrid approach revealed that triage nurse scheduling had a greater impact than adding beds—a finding missed by single-paradigm models.

2. Material Handling Library Stability

The Material Handling Library (MHL), introduced in 8.9, revolutionized warehouse simulation by introducing "Free Space" navigation for autonomous mobile robots (AMRs). Version 8.9.1 addresses collision avoidance edge-cases. Specifically, the AGV (Automated Guided Vehicle) movement logic has been refined to prevent deadlocks in high-density storage retrieval systems. For professionals modeling intralogistics, this reduces model runtime errors by approximately 15%.

Typical use cases

  • Supply chain design and inventory optimization.
  • Manufacturing line balancing, throughput and bottleneck analysis.
  • Healthcare operations: patient flow, resource allocation, and scheduling.
  • Transportation, logistics and fleet management simulation.
  • Emergency planning, crowd management, and facility layout analysis.
  • Policy analysis and system behavior studies combining high-level dynamics with agent details.

Title Agent‑based and discrete‑event hybrid simulation of urban last‑mile delivery under dynamic crowdshipping incentives

Abstract (1 paragraph) We propose a hybrid AnyLogic model combining agent‑based and discrete‑event paradigms to evaluate dynamic crowdshipping incentive schemes for same‑day urban last‑mile delivery. The model simulates couriers (professional and crowdshippers), parcel flows, traffic congestion, customer time windows, and real‑time pricing incentives. We compare fixed, time‑of‑day, and demand‑responsive incentive policies on delivery timeliness, cost, emissions, and courier participation. Results quantify tradeoffs and identify conditions where dynamic incentives reduce costs and emissions while maintaining service levels. New Features in 8

Introduction (bulleted points)

  • Problem: rising urban delivery demand; costly and polluting last‑mile legs.
  • Background: crowdshipping as a supplement; need to design incentives that balance cost, service, and environmental impact.
  • Contribution: hybrid AnyLogic model, evaluation of incentive algorithms, sensitivity across demand patterns and traffic.

Model Overview

  • Modeling platform: AnyLogic Professional 8.9.1 (hybrid: agent‑based + discrete‑event).
  • Entities:
    • Customers: locations, time windows, parcel size, willingness‑to‑wait.
    • Professional carriers: vehicles, schedules, capacity constraints.
    • Crowdshippers: agents with schedules, probability to accept tasks based on offered incentive and detour/time cost.
    • Parcels: arrival process (Poisson or time‑dependent), service requirements.
    • Road network: GIS import of a city map or synthetic grid; link travel times are time‑dependent (traffic congestion model).
  • Key modules: dynamic task allocation, incentive calculation module, routing (vehicle routing heuristics), emissions calculator.

Methodology

  • Implementation steps in AnyLogic:
    1. Import city network (OSM) and create Main agent with population of customer agents and carrier agents.
    2. Model parcel arrival as time‑dependent arrival rates (Source block in Process Modeling Library).
    3. Professional carriers modeled with Vehicles (Process Modeling) using VRP solver or custom insertion heuristics.
    4. Crowdshippers as agents with daily schedules, utility function U = incentive − detour_cost − time_cost; acceptance if U > threshold. Implement using statecharts for decision flow.
    5. Incentive policies: (a) fixed per parcel, (b) time‑of‑day multiplier, (c) demand‑responsive: incentive = base + α*(queue_length) + β*(expected_delay).
    6. Real‑time matching: implement auction/offer mechanism—when parcel unassigned within T0, send offers to nearby crowdshippers; model communication delay and acceptance.
    7. Traffic: use AnyLogic traffic library or time‑dependent link speeds; congestion arises from vehicle densities.
    8. Metrics: on‑time delivery rate, average delivery cost (carrier cost + incentives), CO2 emissions (per km factors), average waiting time, crowdshipper participation rate.

Experimental design

  • Scenarios (table suggested in paper):
    • Demand profiles: low/medium/high; peak surge (rush hour) scenario.
    • Fleet mixes: professional-only, mixed with 20%/40% crowdshippers.
    • Incentive policies: fixed, time‑of‑day, demand‑responsive (vary α, β).
    • Sensitivity: crowdshipper acceptance sensitivity, communication latency, max allowed detour.
  • Replications: 30 seeds per scenario for statistical confidence.
  • Statistical analysis: ANOVA and pairwise tests on key metrics; regression to relate incentive parameters to outcomes.

Expected Results / Hypotheses

  • Dynamic demand‑responsive incentives will increase crowdshipper participation during peaks, reducing professional fleet overtime and lowering delivery delays.
  • Total cost will be lower under mixed fleets with well‑tuned dynamic incentives for medium demand; during extreme peaks, incentives may increase costs but reduce delays and emissions.
  • Tradeoff frontier: plot cost vs. on‑time rate to identify Pareto‑efficient incentive settings.

Validation & Calibration

  • Calibrate arrival rates and travel times to sample city data (e.g., parcels per 1,000 households per day).
  • Validate crowdshipper acceptance model using survey or literature values for willingness to detour.

Software/Model artifacts to include

  • AnyLogic model files (.alp), parameter sets, scenario scripts.
  • Supplementary: flowcharts/statecharts, pseudo‑code for incentive algorithm, data generation scripts, aggregated CSV outputs.

Limitations

  • Simplified driver behavior and deterministic acceptance threshold; real human behavior more complex.
  • Quality of road network and demand data affects external validity.

Conclusion (1–2 lines) Hybrid simulation in AnyLogic 8.9.1 demonstrates how dynamic incentives can improve last‑mile performance; the paper provides prescriptive guidance on incentive parameterization and deployment tradeoffs.

1. The Fluid Library (A Major Highlight of the 8.9 Series)

The most significant "feature" solidified in this version is the Fluid Library. While introduced broadly in 8.9, it is a game-changer for specific industries.

  • What it does: It allows users to model the storage and flow of fluids, bulk materials, and gases.
  • Why it's interesting: Previously, users had to use the "Material Handling Library" or write custom code to approximate fluid dynamics. The Fluid Library provides drag-and-drop blocks for tanks, pipes, valves, and pumps. This opened up AnyLogic to far more complex use cases in Chemical, Oil & Gas, Water Treatment, and Mining without requiring external add-ons.

A. Healthcare Capacity Planning

Hospitals use the Agent-Based and Process Modeling libraries to simulate patient flow. With the GIS improvements in 8.9.1, analysts can now model ambulance dispatch based on real-time traffic data pulled via the Road Traffic Library, reducing emergency response times by modeling "what-if" scenarios.
